My pleasure! I tried it a couple of times just to make sure it was consistent. :P I've completed all the attainments except that one now!
Other notes:
- The chained-squares mechanic seems to interfere with leveling up units. It might have to do with whether I line them up using my last available move, but I'm not sure. It doesn't happen every time, though.
- It's also weird that the chains prevent distilling and discarding units when neither of those use up moves.
