I just installed the B19 version into my latest game and I have two red squares with X's in them that have appeared (see picture). Mouse overing the square reveals the stat N/A %
I'm pretty sure they have something to do with this mod as they appeared immediately after installation and are located only over sqaures which were empty shelves to store organs.
I have moved the shelves, built new stuff on the square etc and they stay put.
Reloading game has no effect.

They dont seem to affect the game but any idea what they are?
