I've been curious about this as well. None of the new runs are options, nor the new treasure maps. I can maybe see the runs for spoiler purposes, (Maybe? I don't know how a name alone could REALLY spoil it, but that's the only logic I can see there), but why are the new maps not an option?

The only reason I can see here is that they've been too busy with everything else and haven't had the time to update that option? But adding a few names to a list doesn't seem like that hard of a thing to update to me.....
