Where's the Missing Era Currency?

It costs 244k era currency to take a character from level 0 to level 65. 

The episode track has 48.5k (and that's for two characters). Coliseum doesn't seem to have any. F2P marquee tiers have a few hundred (enough to get to level 5).

 So where's the other 220k coming from? Are Era Challenges going to be giving ~150k potential each? Or did someone at CG forget to add it to the daily chest or drop a 0 somewhere?
