Some Dungeon-rooms are still not decorable

If you buy a Dungeon Entrance at the crown store there are recipes and blueprints included.

If you build this rooms most of them have still no sence,
because neither you can decorate them (a.e. the Dungeon Stone Room 24*24 with two entrances) nor you can spawn monsters in there.

So you just need granit and other crafting stuff and offers blueprints which you cant buy on another way then with an entrance at the store just for an piece of sh...

This "bug" is in the game since the dungeon-entrances are released and I try every second release if they are now decorable, but no response from a dev.

So pls ... can you have a look on that.
