I have 3 game saves  of which all 3 are different races.

At different points within the game, between turns 85-128 mark I am experiencing an issue where I complete a battle, click end turn and then a new battle window opens, but not correctly. 

In the first instance; the pictures of the enemy fleet do not appear and the little hour glass in the bottom right hand corner constantly spins stating that it is waiting for the enemy fleet to choose their tactics. 

If I minimise this, it re-opens; this time with the pictures of the enemy fleet but the hour glass remains spinning and the same text appears when hovering over it. 

The auto-save leading up to this moment does not load when I try to reload the game from the auto-save, and if I go back to my previous turn via an older auto-save and repeat my actions leading up to the bug; the same issue occurs every time.

Has anyone seen this issue and does anyone have a fix?
