Hmmm never happens to me.. 3 things jump into mind:
- You are accidently hitting your weapondrop key on the keyboard (so try with your hand away from the keyboard)
- Your mouse 3 button is binded to weapon drop (so you are accidently clicking it when scrolling)
- Your scrolling is binded (by an alias?) to do that automatically.. so check your unnamedsoldier.cfg or any other .cfg you might have in your main and/or configs folder.
Does it happen all the time, or only sometimes when you do it?
theres a
g_immediateswitch
Which skips the putaway weapon anim , that makes it slightly quicker when changing weapons, but it doesnt cause the weapon dropping thing.
I just tried it myself and just managed to do it and it comes up with this in console
Taking ammo pistol away from player
player::Sentient:eactivateWeapon : Tried to deactivate a non-active weapon in hand 0
So it took the ammo but the gun drops aswell.. But yea it happens randomly for me i couldnt do it again
