Pressing NumPad 1,2,3,4,5 or 6 breaks the scripting. At least it does for me.

Noticed it by accident since i usually play using arrow keys and numpad. Today i made a new profile, jumped in with default settings and had no issues. Switched back to my default profile, with default controls and again no issues.

Anyone want to confirm this?
Load up semper fi or die, press NumPad 6 and see if it triggers the gunship explosion.
Or if you prefer MOVE UP, GOOOOOOOO! press NumPad 4.
