Did your admin go on the server and reset persistance ? If it is a private hive they released the package to fix/reset persistance on servers if it brakes down, our hive now correctly keeps vehicles in place. I have yet to find a tent to verify that tho lol. (Tent persistance).

What Ingal just said +1. Noticed that while hightailing away from it I was panicking trying to pull my gun out after clearing my hotbar, after a while the infected just slowed down and started walking along like it's tired. And running -does- affect everything you do. Tired as shit = missing alot.

Must also be noted that you can move trough theese areas on your character, just not in a vehicle.

It doesnt seem to be related to driving or running in general, it just happens after a while no matter what you are up to. You could be running/standing still/ride a truck/eat food/bandage yourself and it still comes up. - Retried and verified.

I'm not having any rain, and I got the same issue, dual 670's running along doing nothing will drop fps completely and ultimately crash/stall the game.

Same issues, totaly unplayable after 5-10 minutes, enjoyed it for several hours yesterday.

They are not good at updating this info on the steam forums either. Everytime there's a release there's a patchrage and people creating 2000 threads over the same matters all going "what who why where." +1
