So I reinstalled Forge to get the Weather2 mod, and something's going wrong with CoroUtil. I have no clue what it is. Here's the crash report. I can't make sense of it.

Dang it. Will it ever get fixed, if you know?

Contact the mod author.

bump

Well, I've been seeing many people with the same problem and apparently the mod author is ghost silent when it comes to contact, and I was wondering if someone had fixed it.

You think I'm stupid. I'm using the latest versions of everything.

Have you even tried updating to the latest version?

Honestly, this issue doesn't matter to me anymore. What I really need help with is my latest thread. If you want to help there, please do. The thread is called Aaaand it crashed.

SSame thing happened to me except i downloaded it on modrinth, i was trying to get Zombie Awareness for fabric, and it didn't work, I think it was the latest version of both mods and Minecraft, before i saw this i just thought I had too many mods, heres my full list of mods (before i installed the two) is: Biomes O' Plenty, Do a barrel roll, cicada (i think i remember for do a barrel roll) Cloth config, distant friends, of course fabric API, Glitchcore, Just zoom, konkrete, not enough cursedness and Terra blender for Biomes o' plenty, plus my three other ones i put in a folder on my desktop outside of Minecraft, which are, fabric api for a different version (1.20.3), Immersive portals, and from the fog.
