4.2 latest build game freeze

Hi,

I've suddenly got a game freeze which I can only end by using the task manager to kill the game. Here's a link to the save:

If you (or at least I) take the fleet next to Fedyadarus 1 and try to destroy the shipyard - or indeed the enemy ship  next to the shipyard - then the freeze occurs.. I validated local files and restarted but it's still happening.

Please would people see if you can duplicate and otherwise I can send more info.

Cheers,

Jon

(Have just moved the fleet in a different direction (NW) and it seems fine.)
