Crash java.lang.IndexOutOfBoundsException: bitIndex < 0: -1

[DevJake]

Have been having this issue for awhile, I'm in a server with a handful of other people with a custom modpack and we all get this crash after playing for awhile and i cant seem to find what's causing it.

here's the link to the crash report, i cant post the full logs because they are too long, there was a lot of warning from compressed blocks but i tried removing it and it didn't fix.

I think its also worth mentioning that when we press disconnect we get the same error type this time it says its a mouseclicked event handler Error: java.lang.IndexOutOfBoundsException: bitIndex < 0: -1

Make a test without Embeddium/Oculus and all related mods, like Rubidium Dynamic Lights

[DevJake]

I removed all related embeddium and oculus mods, i just tested it by disconnecting and the error happened again.

heres the report https://pastebin.com/1kcR5wAt

 

EDIT: i tried removing xaeros and also smoothboot thinking there may be an issue there, nothing, heres that report too. https://pastebin.com/zQS7i9rM

And without Create and related mods?

[DevJake]

Create didn't work but i did figure out the issue, it was everycompat, my assumption with my coding experience was that since it was index out of bounds there was a mod adding too many items that caused the items index to be out of bounds, now i have to knowledge of the backend of minecraft so it was just a assumption so i just tested removing different mods that added a lot of blocks and everycompat was the problem.
