Simulacrum trial mapclip

I was doing a Simulacrum trial as I accepted the challenge I accidently clicked on the waypoint which returned me to my hideout. When I returned to the Simulacrum I was ported to the previous challenge area which was closed off from the one I actually activated but I could still hit the monsters spawning.

I completed the challenge but the area remained locked off, tried creating portals and entering again but to no avail. Eventually I ran out of portals and lost a Simulacrum trial key due to this bug.
