I've cleared out 5 waves and hit the glowing button, and no exit appears out of the arena. I've tried a few save slots around this because I had the bug the first time I did the arena as well. Now if I load one of those saves the door closes that allows access to the panel behind it. So, my party is now stuck in a room without being able to advance or escape.
Also, I suspect this is also I bug. I defeated Arrok and it said I got the gem, yet the crown did not get a new power. I was expecting it to receive fireball or something along those lines.
It's not a bug, you need to find an exit on the room that is not the same place where you came from.
I'm pretty certain it is a bug. When I beat wave 4 I was able to activate the central pillar again or go to a small activation through the small door that opened up by beating 4 waves. If I then stood on the plate that is behind that small door it would light up a glyph near the main Barrier that was in the center of the map. Then...nothing. Nothing changed in the room to let party leave or activate anything else.
The fact that it won't even let me do that when reloading a save definitely confirms it's a bug.
Ansatu, I hit the same issue yesterday, where upon reloading the door to the glyph closed and there was no way out. So the part with reloading a save is definitely a bug and it's a game-breaker.
But, the "then...nothing" is actually working, there's a difficult-to-see ledge inside the small room behind the door that locks up.
Yo, I`ve had the same issue. I`ve loaded game back to forest, before discovering the hut and fast traveled back to the start of the map, ready to leave. Doing so, triggered additional animation, for some reason. Afterwards, I went to `discover` the hut in that save. Doing so, finally updated the objective to `Enter the Shed` from previous objective. I could interact with the pillar and start the arena fights. Hope this helps.
I'm having the same problem. Completed the waves, the door to the glyph opens up, we go in and step on the glyph, hear the noise of the glyph tile lowering into the trigger, then nothing. No way out of the arena. I've circled the entire arena, every wall, looking for any ledge or crawl through to access. There is none. This didn't happen on my first playthrough. Now in my second, I'm stuck. Reloading didn't help. Shutting game down for the night, came back this morning. Still stuck. I hate the idea of having to go back to my last save at the shed.
I was stuck to in the arena after stepping on the glyph, couldn't climb out anywhere. Then I tried having just ONE character, who has the spider climb cape walk around that little room and he was able to go up the wall to the left of the room when you are facing away from the door. Once he got on that ledge, the rest of the party was able getting up there. Try climbing just ONE party member up it first and see if that works. Good luck!
