In the UAC vaults mission the game crashes.
In the attached save if you hit end turn the ai turn starts as normal, but part way through the game crashes.
This is the second UAC vaults mission I've done, in the first one it did crash in the ai turn once but when I reloaded and tried again it didn't repeat and I completed the mission perfectly. So it may not reproduce every time; although in this one I've tried it 3 times and it has crashed every time.
Only other information is that in the 2 missions the enemies where different so I would guess it's not specific to them.
