Description

I had a new idea to make a world with a lower sea level to remove ore and most stone generation, (y=11) so I was testing with the vanilla customized world type after having no luck with OTG as it is buggy and slow. But apparently I got a crash for ticking entity as the player from the OTG core mod! How do I remove core mods? Deleting memory_repo didnt do anything...

EDIT: actually loading ANY WORLD does NOT WORK!!!!

Edit 2: my bad, its in the 1.12.2 folder. I got it.
