Same. Completed 3 floors, can't enter Test of Time.

Same happened to me when entering the 4th floor. (Trial of Time)

Basically means you lost your entire trial run and you aren't even sure if it will work next attempt.

Also having the issue on 3rd floor sanctum, tried reloading instance with no luck

Same here going into Trial of Time

Same here, just happened 4th ascension 4th floor, full everything, really fun losing the Djinn and time for no reason.

I too am locked in the beginning of the third floor. I suspect its because I went into the third floor after accepting about 8 boons from the merchant and did not allow for the prompts for the boons to complete before going into the next room. Who knows though.

The worst gamemode in the game has a game-breaking bug, feels great.
