In what kind of world or server did the problem occur?

Other (specify in "What went wrong?" section)

What went wrong? (Crash logs don't go here)

The startup screen won't appear after loading the mods, instead it says "saving world" and crashes, or just closes itself without further notice. I believe multiple mods are involved. Just a hypothesis.

Important: I had a mod in suspicion which I deactivated, but after I added an other mod, it happened again. Pehkui showed up relatively early in the crash report so I assume it's got to do with it? I can't imagine why tumbleweed which is not doing anything about the pigs got this issue 🤔 I will send a bug report to everybody else, though that way maybe somebody will figure out what's the exact cause.

"There was an error creating your issue: body is too long (maximum is 65536 characters). " as github says, so please read everything in the attached crash log. I am annoyed I tried to submit it 4 times now.

Did the problem cause the game to crash?

Yes. (paste crash report below)

Full crash report contents (if you experienced a crash)

Issue related to other mods. Minecraft Pig entity was picked because it failed to load other elements and used that as a fallback measure. Linked to Item Registration method. Fixed for SakuraBlossomGrotto, Tumbleweed pending.
Going to close this now. If you wonder about the issue, read more here: Dekunutter/CherryBlossomGrotto#36

Additional info: When I deactivated Tumbleweed after I couldn't start after adding "haunted Harvest" I could run the game again.

I am unsure how this is connected but your mod changes models, doesn't it?

Update: Possibly unrelated to this mod. Crash analysis pending.
