Is there a map or overview of the exact "spawnzones" where players can spawn around byelov?

Or is this secret developer stuff?

Or can anyone say me if ppl can spawn where the foundation is?

Hello, we built a stronghold foundation today next to byelov, and some players are worried about spawning in the stronghold and not getting out anymore. If a stronghold built in the "spawnzone" can ppl spawn directly in the stronghold or is the does the spawnsystem automatically move/spawn...

Disable it, but make sure reinforcing, Jerry cans,... Get a "gear" Option to pick them up.

Will there only be the trader in the patch? When will the new Island between lyepestok and novistrana come along with the new towers?
