I caught this a few days ago. There are some arenas I play in where the stray guns of fallen soldiers still react to physics so they can be kicked into the air by gunfire or explosions. Then other times this feature is nonexistant. Anyone else notice this?

Yeah

Yes this happens....so whats your problem?

you can put it on or off in the soldat.ini file

usually only the gun that the soldat was using at the time they died can be 'kicked around' or even picked up. You might be able to see their secondary laying on the ground but you can't pick it up or do anything to it.
