Game sometimes hangs on making a new world with More Mob Variants installed
Not-February opened this issue ยท 2 comments
I did a thread dump when creating a new world in my modpack stalled indefinitely upon generating a new world and found something weird.
There's an error in that references an attempt at replacing zombie spawners that references both Sully's Mod and More Mob Variants. I suspect both mods are trying to alter a monster spawner in a dungeon and don't know what to do when they interact into each other.

I'm able to replicate this with nothing but Sully's Mod 3.2.1, Blueprint 7.1.0, and More Mob Variants 1.3.0.1 installed. I'm using Forge 47.3.0 as a mod loader.
It doesn't always happen, but make enough new worlds with random seeds and you'll run into it eventually.
Oh yeah I remember experiencing this as well before. Your monster spawner theory is correct iirc, I'll have another look at this in the future!
according to #133 it might also cause crashes
