Stock RCS missing

[GABRIEU222]

I've had this problem were the stock RCS has gone missing. Most of my ships used them so now I have only a few of them still working. I have some mods installed, but I do not know which one is causing that. Any help is appreciated.

@GABRIEU222"gone missing": Please clarify whether the parts vanished off ships in flight, the parts are missing from the VAB part menu, or the parts are still there but don't provide thrust?

Have you made any mod changes recently? Realism Overhaul and Real Fuels change fuel types and I don't know what happens if you add those mods in the middle of a saved game. Try right-click on your RCS tanks and RCS thrusters to see if they are set to use the same fuel type.

If you don't find anything obvious, share your log file. Directions at the link below.
