For some reason, selecting agent/aircraft/ground equipment screen when X-COM has some Autocannon AP rounds in it's stores automatically makes the stores 999% full and appears to say it is both selling and receiving the ammo at the same time
This in turn gives X-COM a HUGE number of the ammo in its stores
Selecting the vehicle store type resets the store level back to normal but from the moment that extra ammo appears in X-COM equip screen the game is not going to let you do anything with the stores...



It appears to be related to the Agent Equip screen when using preset agent equipment... In making an autocannon agent, setting it as preset 3, after a few agents of pressing "3" to equip, suddenly the ammo level goes up on the "on ground"/"stores" part of the screen IF you do not have enough items in the stores... (I.E. a negative value)



I have uploaded a video of this behaviour here:

Note that the bug occurs with NO AP ammo stored at base
I meet the same bug, but with HE ammo.

I just sell all HE ammo clips.
Does this still repro? I suspect it's a dup of #639
