Moved skeletal mesh to new computer and this happened...

After moving my project from 4.24 on my old computer, to 4.24 on my new computer, something has gone wrong with a skeletal mesh.
Not only am I getting these artifacts, the model becomes unstable in the skelmesh editor, while accessing some params. It sometimes crashes with the attached error message.

The bottom plate/wheels is a posable mesh, which can be controlled remotely by the player. The top part is a skeletal mesh, with an idle animation applied.

Does anyone have any advice?


You should really install the debug symbols to know what the actual error is.

I don’t know what that is.

Care to elaborate?

Nevermind. I found a backup on an HD I had put away for safe-keeping.

Remember kids; keep backups, because the forum is no place to find answers.
