Player bodies disappearing very fast?

[mansa 5]

Date/Time: On several occasions, most recently today at about 18:00 GMT+1

What happened: I killed a person at NW airfield and before going for his loot I scouted the area to make sure he didn't have any friends with him, after about 1 minute or so I decided to go check his corpse. I opened it up and just got to look through everything he had and then the corpse just sank into the ground and disappeared. I could still hear the flies though. This has happend on pretty much every kill I have gotten lately. Not sure if its supposed to be like this. All in all it took me maybe 2-3 minutes before I got to his corpse and for it to go away. :/

Where you were: NW Airfield. I was in the big radio tower and he was up some stairs in the fire house.

What you were doing: I sniped him and went for his loot after scouting the area. Then his body went away.

Current installed version: I have 1.7 DayZ and the latest ARMA 2 OA beta.

Server(s) you were on: Most recently was on US20, it has also happend on many others.

Your system specs: 8GB RAM, AMD Radehon HD 6950 2GB, Intel i5 3.2Ghz, 1TB HDD. Thats it I think.
