Okay, I want to make certain tanks and units owned by multiple sides, but not all the sides. ( > Russians & Americans, but not the rest.) I first tried changing the owner=. That caused my game to crash
, so I added Required house=. That made the units buildable for everyone, VERY BAD.
So final I added the Forbidden house= tag and now no one can build the units ( tech level is not -1, done checked).
Can anyone tell me where I messed up? please.
