Hello, i've been experiencing a deadlock randomly for a while now, not sure what mod is causing it. The log mentions Moonlight and Animatica; My modpack is very large so I understand how to troubleshoot these issues but this deadlock happens so randomly that I'm at a loss. Sometimes it doesn't happen for days and other times it happens three times in quick succession.

This time it happened after stopping Spark's profiler.

I have Sinytra Connector + Embeddium so I understand if you don't wish to look into it; If you don't think it's moonlight's issue i'll remove Animatica and hope for the best.

1.20.1
Forge 47.3.22
Latest Moonlight Lib

Does that show up on all the times It stopped? The log just mentions what every thread was doing at that moment when it hanged fir more than 4000 ticks

The mixins mentioned there should not affect that so I don't think it's related as even if it was that thread to hang it was happening deep in vanilla code ahead of those

I got a similar crash when loading a world. Game output

The server thread was running the dynamic resource generation for both WoodGood and StoneZone when the Watchdog (from ModernFix) killed things (though the game actually crashed shortly afterwards with some class loading errors which don't happen with just those mods)

I took a look at the latest.log (your link). it looks like the culprit is:
Nyf's Spiders (nyfsspiders), Version: 2.1.1

the error was this Could not initialize class com.nyfaria.nyfsspiders.platform.Services. that's what caused the crash.

I missed that at first. Not sure why it broke as it had been working since I made the pack initially.

Haven't experienced the issue in a long time, I guess it magically fixed itself
