Force-text asset serialization bug in 5.5

Surely there must be a lot of people working on projects configured to serialize assets to text. Since it's in the 5.5 beta, this thread is locked, but I've started getting the same error messages and there are a few other mentions of it around.

https://forum.unity3d.com/threads/asset-with-guid-__-has-empty-path-but-has-assettimestamp.432691/

Asset with GUID 67e9dad5654047ebbe623cce9dbf7b38 has empty path but has assettimestamp???

...along with the other three same GUIDs described there.

It isn't preventing my project from building or running, the errors just display when the project is first opened, but this comment from that thread worries me: "I have some prefabs that are always losing references because of this error."

We just switched to a local git repository (my wife chastized me for the "daily zip file" hobo-repo scheme I was using). Makes me nervous to just ignore this and hope 5.6 makes it all better.

Anybody found a good work-around?

(And, side note, do beta forums really need to be locked after release?)

 

Just realized I might dig up more info if I Googled for the GUID itself.
I guess it's time to suck it up and install a patch. :/
