Description
When using silkworms to infest leaves, everything seems normal until at the 99% mark, the game crashes with the following logs. Not 100% sure this is from FEN but as it only happens when using the worms figured I'd report it.

I'll give it a look in a minute, thanks for the report 👍
I would also recommend installing NotEnoughCrashes, since it both gives a clearer crash log, and sometimes prevents the game from fully crashing (brings you back to main menu in most cases).

I messed around with some of the mods you have installed, but I wasn't able to replicate the issue. It could some mod incompatibility. Would be great if you can provide new logs with NotEnoughCrashes installed.

This is the latest crash log or latest using NEC. I may attempt to do a clean re-install of Minecraft and my modsets. Using AdoptOpenJDK wouldn't have any affect would it?

The crash log link doesn't seem to work, it's either private or expired.
From the log, it looks like something isn't able to create leaf particles. I tried downloading a bunch of the rendering mods you had, but I wasn't able to replicate.
Can you maybe join the discord and send your pack so I can test without having to download all the mods 1 by 1?

Sorry it took me some time to get to it, I'll pack it up with the world, where would you like the link?

Seems like the problem is Immersive Weathering, I'll have to look into why. For now, check if there's anything for disabling the leaf particles.

Actually, it seems to have been fixed in the latest version of IW. Update both mods, and if you're still experiencing any issues regarding this, feel free to reopen the issue.
