Most of the time when this subject has come up, it has been a result of not having enough resources. Even though the resource storage shows enough, many times there is not enough because the person is using a Resource Converter that turn (many times unknowingly because its planet is on "repeat orders"). Resource conversion happens before Retrofits, but Retrofits occur before resouce income. So if the rescource conversion lowers any of the 3 resources too low, it can cause retrofits to fail. Then, your resource income is applied so that when you look at your new turn, all you see is failed retrofits and lots of resources in storage again (from income).
