So, here's what happened: When I ran Cosmoteer, it asked if I wanted to upgrade to 0.14.0, which I did. When it finished, my old mods were still there, and none of them were compatible with 0.14.0. It does not appear in the mod screen, so I have no way I know of to disable them. It also shows error logs for each mod pre-0.14.0. Furthermore, I also tried using @Walt 's "No Mod Left Behind" mod upgrader, which I was successfully able to convert the mods I selected, but they do not show up in my folder when I click "Install mod", even though it shows up in my Library. This is a big and annoying problem to me. Any help?
