Weird Mun orbit change after coming out of time warp

Description

I've got a craft around Mun and I'm trying to rendezvous with another. However, when I use timewarp to FF to make an orbit adjustment, my orbit is radically altered coming out of warp. I think this is reproducible in this save.

Reproduction

  1. Load the JJKSP2 campaign, "autosave_3"
  2. You should be in control of the craft "Vulgaris" in orbit around Mun. It has a 56km AP and 19km PE.
  3. Go to the map and time warp ahead until you are near Vulgaris' PE.
  4. The orbit suddenly goes from a stable orbit to one on a collision course with Mun (suddenly -56km PE!)
  5. Vulgaris is also tumbling

Did the orbit's AP get its sign flipped from +56km to -56km when coming out of warp?

I've had this happen several times around the Mun myself.

Here's a short clip of my PE dropping by about 7km as the time warp ends in orbit around Minmus:

Note; smaller changes in AP & velocity occur at the same point.

This seems to be a fairly common occurrence so I imagine you are well aware of it, but please do let me know if you'd like me to do further investigations.
