Minigun frequently ends combat in a state that menus cannot draw

[HG-Dev]

Hello, AUTOMATIC. Ever since I got ahold of a laser minigun, I've been getting headaches whenever messing with caravans where a colonist has a laser minigun equipped. It seems that at the conclusion of combat, it tends to stop in a wound-up state that menus cannot draw. This causes caravan pawn lists to end abruptly. I'll have more information later as I investigate.

It works in the initial caravan regroup, but not splitting.

In other news, I found an ancient wielding a laser turret barrel.
