OK. Heres what I have done. I started with the Static.ini posted in my first post and then added the default static.ini one titled section at a time and checked each section as I added them. The following sections prevented missions from being saved.

Railroads
Groundplate
Concrete Plate
Blank Plate
PCP Plate
PAC_GRPlate
PAC_ Sand plate
and also the subsection "Plates" from the Kronstadt summer section.
Anyone know why these sections in particular should cos any problems?

Had my suspicions about these; as they are items added by FMB+.
What I don't understand is why the stock maps in Il2 which use them are not afflicted with the problem.
