I know that the transition from 1.16.2 to 1.16.3 isn't fully done at all places and its not supported yet but I still tried to run the mods together.

It seems like RandomPatches is crashing the game when its running together with either Patychouli or Immersive Portals (or both together). All mods on its own are running but as soon as they are combined the game is crashing. It might be because of that early crash (or other reasons) but the game does not create a crashlog.

latest.log (RandomPatches + Patchouli + Botania)
latest.log (RandomPatches + Immersive Portals)

Minecraft: 1.16.3
Forge: 34.0.1

RandomPatches: 1.16.2-1.22.1.2
Immersive Portals: 0.3-mc1.16.2
Botania: 1.16.2-406
Patchouli: 1.16-42

If you need any other informations, please let me know.

//edit: Seems like that bug comes from forge and is already known. I'm closing here.
