*Solved*
anyone having this problem it might be Destruction Mod incompatibility

Found this old post "Cant save missions 4.09 in FMB"

sounds like you have the 'destruction mod' installed..... delete the 'files/com/maddox/il2/objectsstatic.ini' line from your filelist

Deleted the line 'files/com/maddox/il2/objectsstatic.ini' and all is well.

Thanks fabianfred where ever you are!
