There's a bug where +3 scales will sometimes disappear in the first or second turn of a game; not all scales are affected, and it doesn't always happen, but the game I played Mictlan I lost my Growth and one other scale and it took a while for them to come back. They did come back, but it was a shame to have missed out on them for much of the early/mid game.
Hopefully fixed in Domoinions 3...
