Bug with corporation material: Quality = NaN
After building up an integrated corporation, I found that it had stalled around the 30 b/s mark only to find that half of the materials had quality NaN.
The affected materials were all materials that another division produced and exported.
Unfortunately, I can not clean stock because I can not sell the material and dumping is not possible in this game, either. (Plus, savegame editing feels too cumbersome at this point.)
Did anyone else have that bug and were you able to solve it?
