Without looking further into it, I assume you had formed a coalition.
When you are in a coalition the game continues until the points requirement for coalition victory are achieved.
As you were a member of the winning coalition, you received the coalition prize, which in this case is 1800 gold.
Coalition prizes are always lower than individual prizes.
If you had left your coalition and won as a solo person, you would have received the solo victory prize plus gold for each victory point.
This is not a bug, this is the design of the game. You received the correct prize for winning as a coalition member. The second place player received the correct prize for winning second place.

So, you see, first recieve 1800 gold whith 812 points, seccond 2285 (???) whith 85 points, and thirth 1784 (???) whith 84 points! Its strange, dont you think?
