Bug?

Hi, I get this error when I save my skeletal mesh, but everything works when I play the game, cloth physics works, literally everything works, so how can I have an “incompatible skeleton” if it clearly is compatible and works fine? Surely this is a bug

i then get this when i play in editor and then stop playing, so i go to the skeleton, save it, and nothing is changed. but again, everything still works.

Greetings @Syco_locked Are the skeletons being imported from another program? I’d double check and make sure the skeletons are rigged. I’ve had this error(Or something similar before) and ended up having to go back and rig all of my skeletons to UE. It wasn’t the most fun I’ve had. But, it fixed it. I’d double check that to start.

I bought the asset from the ue marketplace, it follows the same bone hierarchy as the ue skel and is advertised as “Rigged to Epic skeleton: Yes”

Also it didnt do it at the start of working on the project , it randomly started happening and ive not changed anything about the skel (all i did was create an IK rig)

Also, today i can play in editor and get no errors, i can compile, save and do everything as normal. It only shows up when i go to the skel mesh and press save, and when i open the project. Ive not attempted to build the game to see

ive also just noticed on the 2nd screenshot i sent in, it says “SK_Goblin1” i dont have a SK_Goblin1, never have and dont now.
