Trajectory incorrectly calculates SOI intercept

Was just trying to get a Tylo gravity assist as part of a Pol Mission. Carefully plotted maneuver outside Jool SOI that would give me a low pass by Tylo netting me massive efficiency gains. Executed said maneuver flawlessly, and my ensuing trajectory showed a very clear Tylo SOI intercept, with the resulting trajectory almost resulting in a Jool capture. I began timewarping, and the moment I entered Jool's SOI, the encounter disappeared. Indeed, Tylo would not be anywhere close to where the maneuver trajectory showed it being- it was rougly 1/4 of an orbit past that point. Obviously, this panned out relatively poorly for Bob Kerman.

Ironically, because it was supposed to be a return mission, I had enough dV to get to Pol, and possibly even enough to get back to Kerbin if I pulled some Jeb-level piloting. However, a different bug caused his lander to explode while he was exploring Pol's surface, so now he's on a permanent radiation-vacation.

Trajectories - especially escapes from Jool and other bodies headed in-system toward Kerbol, are badly broken and have been since before Patch 1. Here's an example from tonight. 

Here's my return from high Jool orbit (past the orbit of Pol). This is AFTER my burn but before I had departed the Jool SOI:

Yet right after exiting Jool's SOI this is what I ended up with:

Sounds like this is related to...

 

Yes- this looks like a special case of some kind of more general trajectory bug.

This is extremely similar to what I encountered.
