Temple of Kopec 1st floor generated without stairs/blocked by walls

Still present in 0.4

It sucks especially that I am on T1 waystones and got lucky drop of T4 in the Vall temple. Well my only T4 waystone is now gone in an unfinishable map :(

100% of the map cleared went along walls and into all corners multiple times wasted 20 minutes hoping I can somehow unlock the path.

Issue still ongoing, just happened to me.
