yeah this is unfortunately a bug where if you talk to Beris at any point her floor is permanently set as unbeaten and you can't challenge the third floor anymore. They'll fix it soon I'm sure
This is a weird bug. I can testify it's not guaranteed to happen. Talked to Beris on v24+v24.a both before and after challenging (and successfully going through) her floor… no issue occurred, I can challenge her again and I can move to the other floors.
Well i got it too on 24.a but didnt know until later because i rush each of them and once all of them are done i Come back but the 3rd one is lock i talk to each of them before i Try each level and even redo the second one but it didnt unlock it so idk what to do at this point.
