for some reason, you can't interact with the lighthouses (ki1, 2, 3), you can't open their interface, but you can put the modules using "z", but if you break the lighthouse, they will disappear, if you go to the creative, then the menu will open and there will be a check mark on "does not work" and if you remove it, then everything will work as it should, what to do in this situation?

That isn’t the correct way to use the lighthouses. They work by spreading the effects of the modules you place inside the cores. Please use the Informatron mod to see the explanations it provides or you can look the original mod page about beacons: 248k mod by PreLeyZero

Sorry for the delay in my reply, and if you still have questions, I’ll be happy to help.
