I found a bug that's a pain. It happens when upgrading facilites.

Specifcally with Commercial Radioactive Storage facilities.
WHile on the main screen click on the wrench to view all build queues. Then click upgrade facilites. All colonies with commercial radioactive storage that are due to be upgraded to the next level will be upgraded to the next level of organic not radioactive.

EDIT: I've done some looking in the facilites.txt, it looks like Commercial Organic Warehouse and Commercial Radioactive Warehouse have the same facility family number, which is 1041.

So:

Commercial Radioactive Storage I
upgrades to
Commercial Organic Storage II
