A Few Missing Props

This campaign is almost perfect.  There were a few invisible objects in the way when I played this.  There were places where the bot players had a tough time navigating.  They teleported through many of the objects.  They were able to use all the items and ammo piles.  A few of the Tanks attacked without warning.  One Tank did that after I blew up Whitaker's gun shop.  A Tank climbed over a diesel truck and hit all three bot players with a car.  I thought we were all going to die.  I managed to kill the Tank and save one bot player.  The finale was perfect.  I wouldn't change anything about the finale.  This campaign would be as good as Dead Industry Fixed, No More Industries Extended, and New World Order Extended if something could be done about the invisible objects.
