I was in music1, and the shaman put a portal down, we went through it and ended up in the corner, not being able to move. Good thing i was in fullscreen. I could see the shaman was putting the portals to where we were but it wasnt sending us back, I did not get any pictures. But take it from my word. Was this a glitch with portals, or was it supposed to happen?

Sounds like the old 0,0 glitch. It's not related to the portals however but probably triggered by something else.
