Breach pinnacle Bug

Just finally got enough breach stones to do the pinnacle fight for the first time on the Dan of the Hunt server loaded up. The stone in the portal went to the endgame content activated the hand to start the run and nothing spawned no monsters nothing so literally my countdown timer went to zero why ran through the platform until I had a dead end because I couldn’t progress anymore because I didn’t kill enough mobs I literally been saving up all those stones and now and back to zero because the endgame pinnacle bugged out while doing it.
