Basically, we had fulfilled the requirements since forever, but like a couple other historical events, it never fired even when it should've due to a coding hangup. (It's a reskin of the Ottomans' janissary coup, like the meczenniks as a whole are of the janissaries.) Figuring we could use the variety anyway, I kinda forced the disaster to start ticking, and then roleplayed accordingly in the lead-up to it.
