Multiplayer workaround only !
In a "pure" BAT-JTW - Linebacker install, (Aug. 26th, 2018),
I found the following aircraft will cause some problems from
the multi-player/online "Arming" screen:
F9F8_Cougar
F9F8T_Cougar
F-100D
F-100F
F-86F25E
F-86F25L
SabreMk5
SabreMk6
SabreMk32
G91R1
P-51D-20NA
A-1H
A-1J
A-1H_Tanker -Not causing obvious problems
but it is not in QMB or FMB.
SpitfireMkIXe
F7F-3N -Shows up in Arming screen but
still causes problems
Mi8_Terminator
Mi8_TerminatorAI
a) Those aircraft will not show up in the Arming screen,
(you just see the last valid aircraft you hovered over).
b) The Loadout window shows up blank on those planes.
c) If you chose one of those aircraft, you cannot fly it and
you'll be unable to choose or fly anything else.... shut down,
restart game to fix.
If you still cannot get into the game, switch to BAT-WAW,
create a MP server (local is ok) and choose another aircraft,
hit FLY, end game, reload BAT-JTW and you should be ok.
I'm about to edit my air.ini for my online BAT-JTW and cull the
offending aircraft, then share the file with my MP buddies so we
at least won't have our games crashing while selecting aircraft
from the Arming screen.
This workaround will not, in any way, fix BAT-JTW for online use.
It just helps to avoid some critical issues if you do use it online.
I suspect the cause of this particular problem is weapon loadouts
available for these aircraft, but this is only a hunch based on why
the SabreMk31 works and the SabreMk32 does not, and the fact
that the Loadout window is blank when these aircraft are selected.
