You are absolutely right and I apologize. You need Stellar Manipulation level 30 to close them and level 35 to open them. Good luck I never play with that option and now I remember why.

Guys I'm dropping this debate it is pointless and insulting to think in 400 years no suitable power source has been created and the one that is used uses supplies to make energy at the exact moment the weapon is fired. That is like me shoveling coal into my laser leveler just to hang another picture for my wife!
