I just got a "new" computer, but it requires me to download Legacy Edition to play. So, I did, and I figured that as long as I got mods from the version used with Legacy that it would work fine. I did this with MC Command Center, then all the other mods I got had a version specifically for Legacy. So I turned on Script Mods, exited my game, installed the mods, and left. But it didn't work! It didn't even say they were installed when I clicked "view custom content" in settings! How do you do it?
