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.
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?
