Approach vectors and FMC route
-
@jmarkows For the Bilbao-Pamplona flight the flight plan was as follows:
LEBB
SANTU
D278J
D013J
BISKA
BAPOR
BAGAS
PODUX
PPN
CF15
FI15
LEPPThe point at which the 'FPLN DISCONTINUITY' occurs on this flight is BAGAS, which is the transition between the DESCENT and APPROACH phases. It happens on all flights at this point.

@majick Ahh, now maybe we're getting to a cause.
Discontinuities are very common when entering plans into an FMS and must be manually cleared. If that's where your flight plan goes to hell, that's probably the issue.
To help you clear it I'd need to see a picture of the FMS screen, what's right before and after the discontinuity. I won't have access to my computer with MSFS until next week so I can't load it up myself and look.
Usually discontinuities that appear there have duplicate waypoints, in this case
BAGAS
DISCONTINUITY
BAGASWhere you would press the line select key next to the second BAGAS to "copy" it to the scratch pad on the FMS and then "paste" it over the first BAGAS by pressing that select key, then EXEC in order to "enter" it. This would remove the duplicate and fix the discontinuity. If that's the case here, that's the fix.

@jmarkows I thought I had made a breakthrough this morning based on what you said yesterday.
I actually took the trouble to check the flightplan which was imported from MSFS and lo and behold there was a discontinuity at VIBOK (flying from Pamplona to Barcelona this time..). So I deleted it and made the flight.
I got past VIBOK, and everything was fine. But shortly afterwards a new discontinuity appeared, and this one couldn't be deleted ('INVALID DELETE'). As an interesting side note on this flight, after the discontinuity appeared the pop-up map would open up frozen and with no route at all shown.
It looks like there is a consistent bug when importing an MSFS flight plan, which always puts a discontinuity after the nav point where approach starts. Although it's possible to delete it, the flight still messes up soon after that point.
As it is 100% consistent for me I'm surprised no-one else is having this problem unless I'm the only one on the forum not using some third party flight planning tool.

@majick It sounds kinda like you are trying to delete your discontinuities Airbus style. Did you "delete" the discon EXACTLY like how jmarkows has suggested? (i.e. copy the waypoint after the discon and pasted over the waypoint just before discon?)
