Cold River Map BUG or what?

Hello GGG or to anyone,

I'm in Cold River map specifically in the Boss area. I died once and tried to enter again to finish the boss. I was in loading screen then went straight to the log-in screen. Been logging in back and going to my hide out and trying to enter the portal again to the same map. But it keeps disconnecting and going back to the log-in screen. Trying it for 5 or more times now.

Can someone Clarify the issue that is happening? Thankyou

oh if I accidentally put the portal there. There's no more way to go back inside the map?

okay thankyou. gonna try to run another cold river map again and put a portal nowhere near the stairs ahaha
