RCS stops working

[Cavscout74]

I've never encountered this before, but I had RCS quit working in the middle of a gaming session today.  The RCS does expend monoprop at its usual rate if I try to use it, but there is no visual effect & no thrust applied.  The first time it happened, I tried exiting & reloading the save, with no change.   Then tried exiting the game & reloading it, which worked - for a few minutes.  The next vessel I tried to dock, RCS didn't work again.   The first vessel was under crew control & I've previously docked it with no problems, and yes it still had monoprop available.  The second one was a probe and I've not actually tried to dock it before, but it had good comm signal, plenty of MP available.   This is a 1.4.1 install with MH.  I don't have a mod list handy (I'm on a different computer right now) but I haven't changed or updated anything recently.

I haven't run into this problem. You eliminated any suggestion I may have had. If you could post a log, someone may be able to help.
