POE2 Sinking Spire Tower with boss

i cant get up in the tower because there is ltrl no door or anything else to activate one i searchd every wall inside and outside ones there is just nothing , maybe its because season of the vaal or idk but pls fix this ....

this just happened to me as well... while using the unique tablet to be able to select any map in the area of the tower to run...

wasted tablet...
cant use another tablet on second run of map...
