Ship stuck in orbit, plenty of fuel, but orbit won't change

Question

At first I thought the engine was acting like it was blocked, using fuel but providing no thrust (although mechjeb says there's thrust, just no g-forces), however even the RCS thrusters don't make any change.

The orbit is 400x160km, and when I reverted to launch and tried again I reached the exact same orbit. I know the poodle engine does work for a time because I released the lower stage so it'd fall back to kerbin and used the poodle to raise the periapsis. I was trying to get a circular 400km orbit (as I'm trying to meet up with another craft), but once the periapsis reaches 160km all acceleration seems to stop. Thrusting normal doesn't change my inclination, and radially doesn't change anything either.

I'm not sure how much this matters, but when I say it doesn't change it does a very tiny bit, thrusting prograde seems to increase apoapsis to 400.015km or so before it starts bouncing back, and retrograde reduces it to 399.980km before that also bounces back (the thrusting keeps trying to overcome the bounce, but never succeeds).

At this point I'm not sure what troubleshooting step to try next.

Hmm, just looking at the raw craft file, I wonder if the issue could be caused because I created the craft in 1.1.2 before upgrading. However I did edit the craft after it had been built by construction time which should mean that it's considered to have been designed in 1.1.3...

I'm about to generate a report myself. It doesn't seem to be version or mod-related. It's the updated physics keeping you on-rails and thus your orbit fixed.
