Just finished setting up roombounds for my latest dungeon interior however the game seems to be freezing consistently while trying to load it. EditorWarnings.txt reports the following for each Roombound in the interior:

FORMS: Primitive reference 'RoomMarker' (011CF93E) has half-extents that differ from its multibound data.

Could someone tell me what this means exactly? The editor is only logging this error for roombounds in the new interior so I assume this is part of the problem. The interior itself is large, but far from the largest interior I've included in my mod in terms of x,y dimensions. I also include an .ini file with my mod containing the following entry to bypass the standard object limit (which affects mod interiors but not vanilla interiors ... )

[General]
iLargeIntRefCount=999999

The interior does not include any multibounds as far as I'm aware. All other cells load properly without any problems.
