Bug Description:

Detailed steps to reproduce the bug:
1) Go to downtown_filler_06
2) Start an infested clear (easier to reproduce issue when there is a lot of zombies)
3) Make your way up the staircase until you get to the top

4) There should be 3 broken windows where you can see the roof of the adjacent building, stand in front of the middle one and snipe one of the zombies sleeping on the roof

5) Wait for all the zombies to approach you

Actual result: Sometimes the zombies will get stuck in a "jumping" pose.
