Just installed the mod and was greatly impressed!
ganz großes Tennis!

Will stay with this mod - even it`s declared as beta.
...works great with FM Interiors and lots of other stuff;
=>
did left the Interior/submarine folder out as recommented by the author.
I also would like to recomment to others the combined sh3.sdl file provided by @Aces for more compatibility if using lots of mods together:

Unfortunately i had to strip off the zones.cfg file as well from the mod cause of using LRT mod - what will i miss?
