RCS was working, I know how it works. Halfway to the moon my RCS stopped working. I have plenty of RCS fuel, EC, as well as full avionics control and signal. I've tried quick-save/reload as well as relaunch the game.
FYI this is Realistic progression mod, no other mods installed. Fresh KSP install.
Update: After reactivating RCS through staging it will now thrust forward with translation key. Will NOT provide orientation or forward thrust by throttle.
Also, RCS helper doesn't seem to recognize the thrusters on my craft.
