Thanks for the report, fp!
Unfortunately, the game doesn't load, which can be a sign that something strange is going on.
Do you remember what triggered the game end and caused Fleet turns? Provinces gone or 3 piles empty?
I tried a few scenarios (end on 3-pile, buy last Province in first fleet turn and vice versa), but all of them worked out as they should. Your kingdom had Experiments and Encampments, which may fool a player into thinking the game is over to early on a 3-pile, but this shouldn't happen to the game.
The empty piles included: Province, Curse, Encampment/Plunder, and Nobles. The Province and Nobles and Curses were emptied on the "final" turn, triggering the Fleet turns.
When you say the game ended abruply, I assume it ended after the first fleet turn, or did it end mid-turn?
From the Dombot info it seems that nasmith99 started the game and it ended after a turn they took. Can you confirm this?
I believe it was mid-turn. nansmith99 did not appear to execute a full turn (those turns were long). That is, I beleive the game ended in the middle of the first Fleet turn.
I vividly remember that the game log listed the turn (before crashing) as "Fleet", however, unless I am missing something, I never got my Fleet turn.
