Specs, and is running the normal 2.0 Permafrost. Current guess is a linux interaction weirdness, but unsure. Needs testing.

Looks like a can'tfix issue, something to do with a SereneSeasons check. As the bug only occurs every 2 hours and 40 minutes (on my machine) I don't see this being super high priority. Will check to see if Gunther has it occur more often than that.

Closing, assuming cantfix.
