So uh...Does this mean I automatically win the house event, or lose it?

It let me pick all 4 houses at the beginning. And...Well,

I've had people tell me this means I'm with warbands

But then this really confused them

And apparantly I wasn't supposed to be able to do this???

Some input from Riot would be nice. If I were to get hardlocked into just one house I'd 100% prefer warband, but at the moment it seems like somehow I'm all four. Which has...Weird, implications, regarding rewards.
