Hard Crash - Rare

[Idialot]

I have encountered a hard crash twice now and believe I have recreated it with a 3rd crash. Won't know till that situation arises again to see if I can do it again...

Seems when I send a group of units to take out a hive is when the crash occurs. Twice this has happened under the same circumstance..

Several units take out the hive but have no movement left to actually take the region until next turn. Once next turn has processed moving a unit to take the region results in a hard crash. Black screen no sound or video, have to turn off machine to correct the issues. Seems I have to turn on machine twice as first restart fails with black screen after normal windows crash screen.. "Start Window Normally - safe mode etc." machine wont start. Turn off again and machine starts normally.

Have checked system and video drivers are up to date as well as sound drivers.

Thanks. I can return to the game with no problems to the last auto save and all seems fine.

I have made one modification to the world files to increase map size to 112x112 to increase the map size which seems to be working with no other negative affects.

Thanks
