Vaal Temple Bug [4,202,065,121] - Placing room to branch path created block of inaccessible rooms

Note the block of inaccessible rooms with the red border in the screenshot below. The room with the yellow border was added in an attempt to bridge the gap between the rooms north and south of it. The room with the light blue border already existed and had open paths to all other adjoining rooms (west, east and south). When the yellow room was added it destroyed the 3 existing paths of the light blue room and created this inaccessible block of rooms.
