Possible EOFException in SerializedPersistence during recompile

I have a custom /warp command that reads the "warps file" (yaml). I've used it for literally years (2015ish) and today it randomly threw an EOFException when trying to read the file, but the file is intact.

Could not reproduce, subsequent commands, even identical, worked fine. My guess is a race condition that's going to be nigh impossible to solve. Maybe I shouldn't even bother reporting if it's not reproducible?
