In this bug on DoggySammy's character, you'll see that a fleet of corvettes are stuck in phase space. He tries to scuttle them after being stuck over five minutes, then they started moving again.

Here is the save game file:

This replay shows a couple of serious bugs.
First, the units don't do ANYTHING in the replay, but you can see in the save game file that the game was, in fact, progressing and we were doing things. Apparently, the replay saving is broken.
Also, there are minidumps at the 13:57 mark. It doesn't matter who is watching it, but Steam and SOASER WILL crash if you watch it.
So for regular users, don't watch this. Devs can figure out what's going on with it from the information provided, I suppose.
-edit
I wonder if the minidump is the point where the desync happened.....
