The only script I have running is the one I wrote to add turtle compatibility with other mods' tools, and it does work, but I get spammed with "a tool with the name xyz already exists" when I load a singleplayer world. This didn't happen when I first added the script, but I'm not sure what I might have changed before it started happening. It took me a while to report it because it's not game-breaking, it's just annoying.

Sorry for taking so long to look at this!
