found an error, can you tell me how you can solve the problem *? I'm ready to change the code myself and try to fix the error

Cycle in Technology tree detected.
One of the technologies on that list has Utility Science Pack as a prerequisite(And presumably costs that science pack to research), however, Utility Science pack requires a technology dependant on it.

Short answer to fix: Remove Utility Science Pack as a requirement from all technologies on that list.

thanks! Delete lines in Momotweak mods in Utility Science Pack
normal functionality in you mods!
