Both ammo-types now have a time-of-life limit. If you do not know what this is, don't worry about it.

Fixed issue with weapon pulling ammo through conveyors.

Removed the placement restriction of one weapon per grid - you now may have infinite until your game crashes or audio explodes your eardrums.

Added "time of life" limit to bullets to fix an issue where tracers wouldn't despawn. You should no-longer have floating tracers sitting there while they smugly ruin your immersion.
