I've been enjoying the new 0.58 patch until this weekend.
I logged in to find my character dying from hypothermia. The strange thing is I was healthy last time I logged out.
I immediately starting running to a camp site I'd set up on the server I've been playing on. I'd stock piled tons of supplies and military weapons since 0.58s launch. When I got to the camp site I found that everything had disappeared. Now I don't believe the items were stolen. I had barrels, tents all spread out and hidden in trees over a wide radius. Nothing remained, not even any items left on the floor so I believe that this must have been a bug.
I noticed my screen was starting to lose colour. Bare in mind I was 'healthy' status and I'd only been playing for 10 minutes. I created a fire using my bandages and crouched next to it. The hypothermia message kept appearing at the bottom left even though I was stood right next to the fire and after about 5 more minutes my character died.
I was playing with my girlfriend and I got her to log into my server to try and salvage anything from my corpse. Unfortunately it had disapeared after only 20 minutes and she also logged into the server with hypothermia, dying within 5 minutes of playing.
Hopefully this one will get fixed too as it just puts you off even attempting to play knowing that at any point you could just log in and die of hypothermia for no reason!
