If your bullet belongs both to the Red and Blue families, then you can pick by Red, and spawn Blue
You can spawn a family? that's weird, what if there's more than one object in there? which should be spawned?
hmm.. testing....
okay so that's funny. Sometimes spawns one, sometimes the other, sometimes both, sometimes THREE OF A KIND. I'd guess that's a bug
Also, try spawning from a family. That's also funny.
Doublechecking.....
spawning a family spawns a random object in the family, the numbers were because the spawner was in that family, thus the newly spawned would spawn some other objects also.
But if you spawn from a family, Construct crashes.
I'm filing this.
