the demo crashed once for me while doing the world war, tried to end the combat phase and it said i had a unit that could fire, i clicked the fire button and the game froze (tho i could still move the mouse) Not really an issue but thought i'd post it.

could you please send to us full collection of files (autosave, log)?
if it is possible to reproduce this bug of course...

not managed to reproduce it yet, i know it was a transport that had units in it that could attack, will keep trying tomorrow.
