I just started playing again after a long hiatus today, cant live without my B9 parts. I have searched but haven't found any one else with the same issues. Some of the Mk2 plane parts are miss aligned when they snap to each other. Has this been a resolved issue or something new I am doing wrong ? Any help is appreciated.

Love this mod but I currently have (one of many) a KSP ver 23.5 game with RSS 6.4x config and the smart parts dont function I get the apiextentions warning pop up when I start, is there a link to an older version of smart parts that will work with 23.5 or is there quick fix for this?
