Suggestion: Armory Doors have flaps to be critter proof

[Silent Majority]

at least once a month, and often more, particularly on cog 1, I find ghost critters running around trying to trigger the NARC to bust open the n20 tank.

A simple fix to this bad behavior would simply be to have 'flaps' under the armory doors so ghost critters, specifically, can't squeeze under them.

I think it'd be fine for NON ghost critters to do so,
