Hello! I've been having a problem which I think is somewhat common in PZ, the map seems to break and I get an impenetrable black wall and can't progress further. It was happen on the other map too. It usually happens after 10min of gameplay. Does anyone know a solution? I've tried to open ports on my firewall from what I read on another forum but it din't work and all ports seemed open by default anyway. Any help would be appreciated. Cheers!
