I downloaded OTG, but upon experiencing problems with loading the Minecraft launcher, I was prompted to remove it.
When I thought I fully removed the OTG file, the Minecraft launcher always crashed when I ever tried to make a new world, saying that OTG was still in use in files.
Any help with this? Literally cannot play 1.12 anymore rip,,

In the mod folder of your usual version check in the version specific folder and delete OTGCore.jar if found. Heres some examples. It's in the same place if on windows.

Hey, thanks for reporting this, this is a know issue, will see if I can improve this for v8.
