Thanks for the report. The warnings Layer is being removed but it was not present. should be benign and will be removed in the next game version. However I was not able to reproduce a crash. Can you help us identify what steps lead to the crash? If it is a hard-crash to desktop, including unity logs would help too.

If you can't reproduce then I don't know. It was a random crash.
