I'm using 091b001.
After attacking an enemy fleet I found the following:
- the attacking ship had one extra move not expected
- any ship could not move even with moves left (even using find and then trying to move)
- I could interact normally with the interface
- saving, quitting and reloading didn't solve
- pressing the turn button resulted in a turn button freeze (no turn button back on the interface) even if I could use any other function.

I have the game saved in quicksave. If you need it, please tell me what directory to send.
