[2020] Crossbow ammo pickup glitch

The first ammo pickup for crossbow always shows +2 in the status bar, but only one actually goes in my inventory. This only happens on the first pickup when empty- the other pickups give 2 rounds until it maxes out. In other words it takes 4 pickups to max out the crossbow ammo. Doesn't seem to happen with sniper or grenade launcher special ammo.

I first noticed it several months ago and it happen every time. Not a big deal but finally managed to get a screen shot of it so thought I would mention it.
