So...Forge 12.2 I'm having trouble getting through the crash report, My launcher instantly says my game crashed... How do I turn Opti fine off. Because I think that is the issue. Because I read from another post about 1.12 forge not working. Pls help when have time... I'm trying to use it for a schematic mod for a server. With lunatriucs and schematic.
