Bug–won't recognize enough treasure

I got the little “You’ve found enough treasure to return home” ages ago when I finally hit 5 pieces, but kept mining and collecting. Now, when I take my treasure (7 total pieces) out of the chest I’ve been storing them in, I don’t get that message. (In earlier versions, I would have done.) When I try to sail away on my bull boat with all my treasure in my inventory, it tells me I don’t have enough treasure to return home.

I still get the “you discovered treasure!” message every time I take a piece out of the box. I’ve tried save-and-exiting with the treasure in my inventory, and that doesn’t fix it.

I tried putting all the treasure on the ground, exiting, reopening, and then picking up my treasure from the ground. That did not fix it.

I tried putting them all in a backpack, laying the pack on the ground, exiting, re-opening, picking up the pack, and taking out the treasure. This did not fix it.

Have you changed the amount required to win, and I just imagined my first “congratulations!” message? Or is this a bug that makes the game unwinnable?
