Things are mostly going smoothly at the moment in my Mastercraft embark, right up until just now.
Yesterday I happened to get a barrel of the Tears of Armok drink from sacrificing some spare meat at the altar. It took a while for one of my dwarves to get around to drinking any, but I received this message today:
Zulban Idenngubmul, Woodcrafter has transformed into a fully healed creature!
Zulban Idenngubmul, Fully Healed Creature Woodcrafter has transformed into a dwarf!
Zulban Idenngubmul, Woodcrafter cancels Drink: Job item lost or destroyed.
It seems that her drinking was interrupted so thoroughly that there were still 5 units left of it in the barrel. I wonder if it would ever be finished.
More worryingly, when I examined her to see if she looked any different, she'd aged about 150 years, to long after Mastercraft's reduced Dwarf life expectancy of [MAXAGE:90:110] would want her to die. I've no idea if she would have died of old age in the near future. As I'd just started my evening session I decided to restart instead, and forbid the Tears of Armok barrel, as a barrel of ale that is never used up and ages everyone beyond their life expectancy sounds kind of fortress-killing. I may be mistaken in thinking it's dangerous, but I think I'll put it in Vault 13 for safe-keeping (or sell it to the elves).
Edit: While pulling the above bit from my gamelog, I found this little gem from one of my false starts while figuring out Mastercraft features.:

I don't even remember what happened with that one. It sounds quite thrilling though.
