I have played a lot today the new version 16.1. 16october 2012
I had a lot of crashes.
I have a current play session going with no crashes.
I have been through 3 farm maps now. A lot of local forces vaulting over things. Civilians just doing a duck and cover, no vaulting.
EDIT:
4th try on a farm map and I got a crash. A lot of civilians here. One where vaulting over a lot of things. But no vault animation instead he was like floating through the obstecles.
Then I got a random crash on hidden movement screen and it did not seem to have anything to do with vaulting over things.
