@Bod Thanks, if the jobs do not like, I always remove them.
This is useful and I leave it.
For the doors, I've created both animated and non-animated ones, so those in the upper floors leave them still.
@UndeadJoe Thanks, you have to work on some scripts to do that, but it would be okay. good idea.
@Wolf, @Tarkus1971, @devlin, Many thanks.
