Stuck Inside Halls of the Dead arena

I was in Round 7/Final Round on Halls of the Dead arena. When I was pushed to the wall with I think Tidecallers wave or something whilst trying to dash out of with a whirling blades. So I got stuck in the torch-like post on the wall as seen in the image. I still tried to win using my raging spirits and with just my units and won the last round but was still stuck. I tried to unstuck my character by using whirling blades and using other skills. I even tried the so-called /oos command to try and unstuck but to no avail. Portals are disabled inside the Halls arena so I could use one. My poor 15 chaos orb reward and I wasn't able to see the reward choices that could have been for winning the last round. So I had to go to character selection just to get out of the instance and my character spawned in karui shores with no rewards. It could have been worth nothing or something I couldn't help but wonder. Being new to the game and having to experience something like that just makes me sad.
