Same bug here. Although happened with me after retiring some heroes. I suspect there's something wrong with script that updates building options

same bug here, could be a submod or something, idk

Hi, if the build options for all tabs except ground disappear and the planet info in the top left stops updating, that is in all likelihood a framework crash.

If the scripting crashes, there is nothing you can do to ♥♥♥♥♥♥ it, so you'll have to load an earlier save or start a new game.

If you find that the framework crashes consistently at a certain point, like after a certain research or event, please head to the Mod's Discord and put a bug report there.

Usually the best thing when starting a new GC is to wait another while after controls unlock before clicking a lot through the AI so everything can load in properly.

Custom GC can also crash the framework a lot if you're not careful during setup.
