hey guys, I'm hitting an issue where some of the Remote Tech parts are no longer "showing up" in game. I can load existing craft with the Reflectron DP-10 and I can see the part while in flight, however I can't interact the part (right click) and doesn't seem to work (no craft control when it should). Most significantly, the part does not show up in build mode at all while the Communotron 16 and DTS-M1 do show up. I've tried a clean reinstall of Remote Tech; no dice.
