0.4.0c Vaal Temple Bugs

So i already found 2 bugs, first one is that the additional rooms that can be placed via medallions wont show theyr preview icon. you can see the dark green and light green indicators of where to place it, but not like with other rooms the effect that placing them has (increasing its own room level or the level of adjacent rooms).

2nd but is i cant use the royal access chamber even if the throne room is connected (via the newly added possibility to connect to it via special rooms)
the royal access chamber cant be interacted with, and the adjacent room has no passage that leads into the throne room even if the map indicates it

did another run right after, directly connected the room this time and it worked, so it does indeed seem that the connection with special rooms is buggy
