Also when i go to Stadium and some mob kill me it's spawn me on Arena, see at the screenshot

I was Trying with change terrain on server and client side but nothing help to fix this problem. 

Hi, either you change the gate on both server and client, or, still in the gates, you have the respawn of the maps and the respawn coordinates for when you die.
