And because it is easy to reproduce it is also easy to avoid

- Start Jutland scenario as the Reich
Select the Naval Detachement in Kiel (3 subs and a Zeppelin)
Select the Zeppelin (L71) in the Units window on the bottom left
Drag the Zeppelin to the Kiel area => [color="Red"]CTD[/color]
When I check for further information I get a window reporting this problem signature:
AppName: ww1.exe AppVer: 1.0.3.1 ModName: unknown
ModVer: 0.0.0.0 Offset: 40400000
It does not crash when I drag it to a different area (land or sea) or when I do the same with one of the subs.
Setup: Sec. Lev. 2, no music, sounds enabled
