All other mods work fine but when I try to use iChunUtil for your mods the game crashes at start up. I’ve uninstalled every other mod and just installed iChunUtil and it still crashes. Everything is at version 1.10.2. Here’s the crash report:

Hello there!
Hoping you can help with this one. So I’m using a custom private modpack and began experiencing a weird issue with the mod «Matter Overdrive». Specifically, rendering issues with phasers that also cause a variety of openGL errors for surrounding players. I reached out to the mod dev with the issue, and even gave him a copy of my pack to take a look. From his research he determined that it was an issue with iChunUtil rendering.
«It seem that iChunUtil is causing the error. They forgot to check if an item’s icon is null.»
He said it might be in relation to iChunUtil and using backtools. When backtools is removed, he found no problem. He also gave me a copy of the log specifically where it shows the issue for reference.
http://pastebin.com/J6h9ec0L
I’m using iChunUtil 4.2.2 (latest for 1.7.10). I know it is not the most current version overall, and the issue may very well be fixed in the newer version. However since majority of the mods I need are 1.7.10, that is where I am stuck. Is it possible to get a fix for this issue?
Does it only happen with Matter Overdrive?
I’ve only noticed the problem when with Matter Overdrive phasers/phaser rifles, but is triggered by iChunUtil/BackTools combination as shown in the log. When back tools is removed issue is not present.
This bug appears to be caused because there is no verification that an item’s icon is not null. This bug was found using Matter Overdrive (the Phaser and Phaser Rifle don’t have icons) but would theoretically also be a problem with any other item that used a custom item renderer instead of an icon.
By Minecraft code convention, no items should ever have a null IIcon, which
is why I never checked to see if it is null.

This, IIRC, changes in 1.8, however, so the check is (or, should be)
present in the 1.8 versions.

Ok so it should be corrected in the 1.8 versions. But as I am still stuck with 1.7 because of mod support, is there a possibility for a hotfix for the 1.7 version?
I prefer to use the backtools mod if I can get a fix, but if not I can just remove it I suppose.
Most unlikely, sorry, again, this isn’t something that is for me to fix.

У меня такая проблема: Я установил 92 мода в сбоку. Она работала. Добавил до сотни и уже не запускается. После этого пробовал удалять моды, делать *аналогичные сборки — Сборки с таки-же размером и кол-во модов. На аналогичных сборках всё катило. А вот уже оригинал не катил. Вот крашлог:

Logs (Most issues require logs to diagnose):
Spoiler
Please post logs using one of the following sites (Thank you Lumber Wizard for the list):
https://gist.github.com/: 100MB Requires member (Free)
https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)
https://hastebin.com/: 400KB
Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.
What to provide:
…for Crashes and Runtime issues:
Minecraft 1.14.4 and newer:
Post debug.log
Older versions:
Please update…
…for Installer Issues:
Post your installer log, found in the same place you ran the installer
This log will be called either installer.log or named the same as the installer but with .log on the end
Note for Windows users:
Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension
Where to get it:
Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraftlogs.
Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge’s log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse’s installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:
Spoiler
- Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
- Make a launcher profile targeting this version of Forge.
- Set the launcher profile’s GameDir property to the pack’s instance folder (not the instances folder, the folder that has the pack’s name on it).
- Now launch the pack through that profile and follow the «Mojang Launcher» instructions above.
Video:
Spoiler
or alternately,
Fallback («No logs are generated»):
If you don’t see logs generated in the usual place, provide the launcher_log.txt from .minecraft
Server Not Starting:
Spoiler
If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.
Reporting Illegal/Inappropriate Adfocus Ads:
Spoiler
Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.
Lex will need the Ad ID contained in that URL to report it to Adfocus’ support team.
Posting your mod as a GitHub Repo:
Spoiler
When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.
When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.
- Open a command prompt (CMD, Powershell, Terminal, etc).
- Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
-
Run the following commands:
- git init
-
git remote add origin [Your Repository’s URL]
- In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
- git fetch
- git checkout —track origin/master
- git stage *
- git commit -m «[Your commit message]»
- git push
-
Navigate to GitHub and you should now see most of the files.
- note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
- Now you can share your GitHub link with those who you are asking for help.
[Workaround line, please ignore]
So i had to install iChunUtil for a mod, all the mods were working fine (except the one i needed iChunUtil for) but when i installed iChunUtil, it kept crashing here is the crash log:
