Cant leave boss arena in T3 map

I just killed the Boss on a T3 Rustbowl map, and after the boss was killed the Arena portals are not reachable to exit the arena, there is a red shadow like wall blocking the exit :D

relogg worked but I dont think thats intended :D

Stupid me tried to portal out before, so I portal into the arena again >.<

Map is bricked xD
