Revelation Will not Launch

  • Tech Support section is for getting help with FTB related problems. If there's a repeatable issue that can be labeled as a bug, then please use the issue tracker for the pack or the app at GitHub issue trackers - If there's no repository for a pack that means that the pack is old and/or will not be updated. Bugs for older packs will not be fixed, unless they are critical.

I stole this post as the exact same thing is happening to me. I have tried FTB, CurseForge, and ATLaunch which I found out use both or the before mentioned. I would like to be able to play and enjoy the game, as of now I am pissed that I cannot play something I just paid for. Anyways here is basically what I have done with no success:

My buddy runs a small-time revelations server for our friend group, and there is roughly 5 of us who play on said server. We have added our own mods to the modpack but nothing special, and none of us have ever encountered any issues with anything. Our other friend who was wanting to join has installed Revelations but can't seem to boot up the game he crashes and gets a crash report with - "net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from GenDustry " in it.

What we have tried to fix his issue:
Reinstalled Java, vanilla Minecraft, the twitch launcher, and Revelations
Have put the ram to 10 Gb
set the launcher to JAR
installed a fresh version of chickenlib
implemented a .class file to fix the lang issues with GenDustry, and even though that solves Gendustry, another mod pops up with the same problem.

*note that the same thing was happening to him with our crackpack 3 server.

We have literally no idea how this is happening as we thought this issue was fixed years ago,
any help is appreciated thanks.

Does this happen when you use the FTB App? If it does, please share the logs as we can't even start to help without them.

Could you tell me how to do that? I am not so tech savvy my friends walked me through how to do most of it.

If you are using the FTB App, one thing to try first is clearing the local cache and then reinstalling the pack, occasionally this cache gets corrupted. To do this, view the pack details in the App then click the "Open Folder" button. This should open windows explorer at the location of your instance. If you then go up 1 folder level you should see a directory called .localcache along with a bunch of folders with random names. select and delete only the .localcache folder (if you can't find it it should be in .ftba/instances/.localcache). Once you've deleted the cache, remove and reinstall the pack.
