Currently, I'm running Forge 1.12.2 (with Optifine) and it works great! However, I want to be able to use another version of Forge along with the version I currently have installed. The reason I installed Forge in the first place was because I couldn't load Optifine by itself for some reason, and I still don't understand why. Anyway, is it possible to have two versions of Forge installed at the same time? I've already tried doing this with multiple versions, but to no avail; Forge crashes everytime. When I go back and look in the launch options, those versions of Forge are still there, even though I've deleted the files off of my computer. If there's no way to have two versions installed at the same time, is the any way to guarantee that the other version of Forge will work properly if I can rid of the version I already have installed?
Thanks!
