Juno: New Origins | RCS control issues

Not sure if it’s a bug or bad design, but I’m having significant issues controlling a small final stage rocket for the Sat mission. I have a short stack rocket, with 8 multi directional RCS nozzles around the body and 2 more on the base by the main engine. Nozzles are set at 0 degrees on the body and mirrored x4 at the top and bottom of the vehicle, with the base nozzles mirrored x2.

Every time I engage RCS control, every nozzle fires and the ship becomes uncontrollable. The only way to stabilise is to shutdown RCS and engage warp for a brief moment. This makes short range manoeuvring impossible.

Design flaw on my part or something else?

Use normal rcs and have them in all axis

@Insanity Thanks. I think there might still be an issue though. I've reduced the thrusters to 4x multi-RCS nozzles, but even in translation mode they still rotate the craft. The Sat docking tutorial mission makes it quite simple, but even when I can get close to the docking port on the next level, with a 0 or near 0 relative speed, the RCS control does not seem to respond in the same way as the tutorial.

Also you only need 4 multidirectional thrusters to cover all axes of rotation or translation.

Upon testing i figured out that the multidirectional thrusters are always trying to translate even when translation is turned off which is definitely a bug.

Update: also applies when craft stable before RCS activation, in either manual or heading lock modes. Build screen shows centre of mass for that stage as being well below the body itself - looks like the CoM is still in the same place as it would be on stage 1.
