Hey. I keep having this issue with my inventory, where I'm stuck at only being able to carry 7kg. I tried using bags, tried using a backpack, and tried reconnecting to the server. Nothing helped at all, and as such, I lost a radio and two boxes of ammo. Along with my IC items, I have four boxes of SMG ammo, an MP7, and a handheld radio, but I can't hold this stuff in my OOC inventory, and it's rather annoying.
EDIT: Here's the picture of the ammo/gun, didn't put the radio on, but that's easy enough to get a new one of. This happened at about 4:20 PM, April 10th on the Outlands server.
