This time I tweaked them in notebook. I opened the atlas files and changed the class name. Didn’t change anything else. This was only done for bugfixing purposes. The unedited Twilight Knight atlas & skel files that you uploaded are causing a problem. The old modified leper atlas & skel files that you uploaded worked perfectly. I’m not sure why trying to change them to be TK files broke things but they seem to be at the root of the problem.
I’ll grab those new files and see what I can do with them.
