Help changing Assault Mech Animation

[wait321]

In the Next War mod for BtS, the assault mech flies around my city when idle (like airplanes). Is there a way to get it to not do that and just stand still like tanks?

It only happens for me when graphics are set to "low". When set to medium or high, the problem goes away.
