MC saves dimension config in level.dat and it cannot be deserialized after uninstalling the mod. As far as I know Forge already solves this issue. Seems that the Forge's fix is broken? If the Forge's fix is broken, uninstalling other dimension mods could also lead to the same result. This is maybe a Forge's issue.

The quick solution is to create a new world with the same seed and configuration, then use the new world's level.dat to replace the broken world's level.dat (don't forge to backup the original level.dat).

So, backup the world to begin with, create a new world with the same seed, copy the level.dat and replace the broken world’s level.dat with the new one.

Would it be better if I copied the level.dat from a previous save?

Could I also just use NBT Explorer and delete the dimensions from immersive portals?

[GenDutchman]

This is also for a server, and I can’t see player data in the level.dat NBT, I was looking around and saw some stuff that said level.dat stores player data in single player, but nothing about it storing player data on server level.dat.

Ok Ok, I’ve tested it, using NBT Explored I removed the dimensions in the level.dat file, (I backed it all up first) then I removed the mods, the dimensions in the world save, the configs. All is working now, thanks heaps for the help
