editor seems to be broken

the editor is a huge broken mess after the update. after fixing what was wrong with the rover, the problems randomly appeared after updating, i tried to use it on the moon. Upon load beinf complete the rover coppied itsself into many within itsself that fell apart from each other. When reloading the rover, those engine that look randomly placed just appeared on their own and other things such as the solar panels are in different places. The button to move parts by themselves doesnt seem to work most of the time.....at leqst with this rover. before the update, the rover worked. Built a Rocket after giving up on this after spending over 20+ hours trying to fix every problem that kept randomly appearing (before the update) and the Rocket seemed to work fine, though the rocket was very simple. The update just killed any chance of getting the rover to work.
