[Spoilers] Fintourist and Old Harry have nothing to see here

[Fintourist]

I checked my suttree diplo screenshot from earlier this turn: 90 gold
Now later this turn: 102 gold

Does this mean that mackoti bought the peace with a handful of gold or can you think of other ways how he could have got more gold during the turn? Maybe he razed a barb city, but that seems like a long shot.
