Went and solo ran depth 9 to begin clearance on T3.
I stepped onto the elevator and instead of a heat tally/prize wheel/elevator option I was greeted by nothing. I'm currently locked on the current floor.
The GUI works the same as if I was on the level. I can remove vials, converse with guildmates, talk to myself and explore all the other buttons on my HUD. But unable to continue downward. Just wanted to give everyone a heads up if they tried to solo run and this occurred to them as well.
You can however return to haven through the options tab. I'm going to attempt to recreate the bug.
Bug recreated successfully.
Went and joined party at depth 8. Progressed ahead of the party. Locked the party to solo so no one could join. Progressed through the entirety of the level. Again locked out from any other option than hitting options tab and returning to haven. Can still converse with guildmates and function in literally every other way than is intended for the elevator.
This occurred on Sapphire Titan gate, depth 9 twice in a row with the exact same conditions. If you need any more information feel free to ask me questions. My suggestion is to not go solo. Ever. Until this is fixed.
