Rockets get stuck in orbit if selected rocket platform is disabled

Did you press "enter" after renaming the platform? If so, that will disable the platform. Doesn't really answer whether this is a bug or not, but at least it can help you understand how it got disabled. To avoid that, after renaming, just click somewhere else without pressing enter.

Finally someone reported the problem with the rocket platform, the "buried" rocket platform is also unusable, but the lack of information prompts that it does not work correctly is very confusing.
