We finally addressed the main issue since the last bigger update 0.20.0, it seems that freezes that also ultimately crashed the game are gone now.

• Fix: Some players encountered freezes of the game. They are gone now.
• Fix: Zombies that are stuck at a corner of an obstacle will find a way around it after some time now.
• Fix: Blizzard Contrpations stop their sound when they are in standby now.
• Fix: Haulers don't walk on the spot anymore when they pickup or drop off resources.

Known Issues: - The annoying blizzard contraption sound bug is not fully gone, but it appears less now. We will try to fix with the next update.
