I have armour and weapons in buy/sell, but at same time I have 0 of it in 'eqiup soldiers' interface.
Save is attached.
If you go to base 4, and try to equip nanocomposite armour or coil gun to troppers inside the firerbird. It will not be possible, as it shows there no armour nor coilguns, however, you can SELL either armour and two coilguns from the BUY/SELL menu. So actually they are there. And everything was fine till lates updates.
