[LD] Sinister Stones With Accent not properly covering on specific configuration

For some reason, the "Sinister Stones With Accent" wall texture does not cover properly on walls with this specific configuration (single box that extends in an "L"). the left side loads properly as shown in the lefthand portion of the photo.  The center photo shows the error, and the left-hand side shows how it may be "fixed".  Another "fix" is to delete the wall section that forms the "T", opening the single-space box, but for my build that little box is necessary and so I had to sacrifice the way that the rooms were split as shown in the right-hand picture. Originally I wanted them to be split directly in the middle of the "box", but the wall texture wouldn't load correctly without turning the "T" at that intersection into an "X".  I tested this on other walls, on walls that weren't connected with curved walls at all, and I tried completely rebuilding the room, including completely separately from the rest of the house, and I have also run the game with mods on and off, and nothing has seemed to fix this.  Hope the devs see this because it's really frustrating!
