SInking spires : no door, unable to complete the map

I can see this bug still isn't fixed (already reported a few months ago)
Bug ID is 796978672
The map had stone circles, they seem to trigger the boss event and thus make the stairs unavailable to use.

Hi GGG, any idea when this bug will be fixed ?
Another case today with a boss summoning vaal beacon. It breaks the map by disabling the stairs.
Come on, you've already figured out that there is a similar bug in Sun Temple. Please test your endgame.
