Same issue here!

Three of my friend and I are also receiving this error after update .42.

A squad of 4 all experiencing the same issues.

1. Random disconnects (Some were due to battle eye)
2. Waiting for host (Never able to join server)
3. Lag teleporting
4. Running on coast, leg breaks and die instantly.
5. Losing character on server disconnects.
6. Some zombie spawns are less than 10 seconds.

I wish the patch would of been held till it was stable. I convinced a friend to buy the game last night and he was not very impressed after seeing all the issues. This kinda sucks since this is his first experience with the game.

I find them helpful. The main problem is battleeye is worthless and they should look into another anti cheat provider.
This has happen quite a bit lately to me and my squad.
