The new claim block was working fine preventing spawns up till this last patch suddenly we had zombies spawning in our base constantly. We tried various fixes we thought maybe our base was to big because part of the wall wasn't loaded in visually so we made it smaller so the wall was always in sight (witch takes away some of the fun of being able to set the size of the bedroll and claim block no spawn zone). Zombies kept spawning some even spawned right in sight of us. W checked the claim block it was still active one of us decided to put a bedroll down and guess what the zombies stopped spawning inside the base. Makes me think this patch reverted the claim block back to a time when it didn't prevent spawns.
