same thing with the cr75.
and i think i know the problem. it occurs when you want to attach the magazine to the pistol while it is still on the ground and not in your inventory or your hands.
when you try to do this the magazine stays in the slot and is not in the pistol, but from then on its only purpose is to empty it. the ammo then is in the same slot as the magazine.

Ah f*** forgot to mention, i'm using the new ui. Sorry... :/

But i got the feeling anyways that since im getting comfortable with the new ui, a lot more stuff gets lost during any inventory and vicinity actions, or even eating/drinking actions while holding something in the hands.

Thank you.

the magazine was in the backpack.
i had a MP-133 shotgun in hands.
as i recall, i had no storageroom left.
as i said the shotgun in the hands, a CR527 carbine on the back, a magnum, and the 1911.
i just threw out the makarov to pick up the 1911 and change suppressor, pistol flashlight that i had on the makarov. after that i wanted to put in the magazine, but it didn't work, i guess it was a connection problem. (i cant recall whether the 1911 was in the inventory or the vicinity)
but finally i tried to empty the magazine to check if it is still in the inventory or already in the 1911.
it kind of worked. after that the ammunition and the magazine were in the same slot.

with the new ui, never had it with the old one.
no, no ladder, gunshot- and meelemassacres.
was equipped with a few things, shotgun, firefighter axe, some cloths, and each time i died, i could reequipped myself with rags (through "use"), weapons (through "take in hands") and stuff you can split (e.g. ammo, armbands, etc.).

mostly weapons, and stuff that you can split and use (such as rags). you can take it in your hands and from there in the inventory

In my opinion they should stay longer. like until a server restarts or something like 1-3 hours, because it would make sense that someone looted everything then he gets shot, the body gets looted and what ever he still has with him just disappears.

i noticed that too. and it's not like it's black. it's nothing you can't see anything. i have to look away from the fire so that i can see again.

it was gone when i changed the server.
