Half my dungeon is gone

After purchasing the ancient dungeon room pack in the wee hours of the morning i placed all the rooms i could fit, including the blue and green temple rooms and the cathedral. this evening, after logging in, those rooms were gone - though the points are still being used. ive tried removing rooms but that hasnt brought the cathedrals back or freed up the points

EDIT: Resetting my dungeon entirely returned the rooms and the points!
Kind of a bummer to have to lose all that work.. but it wasn't really that much work...

EDIT 2: Rebuilding my dungeon recreated the bug For whatever reason the Blue and Green temples and the Cathedral get lost behind a dead end. If i build another straight wall through it I can get access to the rooms again, but I'm stacking rooms on hallways on top of each other to do this.

EDIT 3: I think the bugged hallway may be the X intersection. If I build hallways "on top" of it I can access the rooms that were behind it but I can never access the X hallway without a full reset.

 

This should be moved to the Player Dungeon thread, apologies.

I reset the dungeon for a 4th time, avoiding connecting the cathedral and temples with an x intersection and have yet to have another issue with disappearing hallways.
