So I did a fresh install of 1.8.1 with just a few mods. Spend all morning designing a refuelstation. Fist mechJeb broke no maneuvers no warping, only node creation worked partwise, secondly I could not click my own orbital path to create maneuvers. And last point, my armed grabbing unit just goes through the 1st meter of the astroid at 0.3ms forward directed velocity only and then bounces back. I gonna uninstall from my laptop again hahaha (dont worry still have it on my Desktop PC)
NVM worked in the end
