Major server bug?

Hello. Why am I suddenly subjected to this error? This referenced file is not even in my currently launched scene.

Is this only project? Or all of yours? Is it possible to share the project?

Ok, sometimes I try to find out a little about the organization behind PC - in this case I wonder if you have personnel that could look into the server integrity,… again (?)
But never mind as I think I have found a solution (not a reason though … still leaning towards structural server issues).
I had taken off two path-entities in a path, disabling them. When I put them back on (enabled) it worked again and the error msg was gone.

Makes little sense that I got the err msg in the first place, though …

Can you share the project and repo steps if possible please?
