Game stuck: Barbarian diplomat tried to desert my unit.

[misterbeebee]

A Barbarian diplomat tried to convince my militia to desert.
I am Greek.

Game says

Greek Militia
 will desert for $24
Treasury $0

$0 is the Barbarian's treasury not my Greek's.
Basically, The game ran the deserter logic for the Barbarian diplomat, but stuck me with the prompt.

Even worse, I can't escape. No matter what I do, the prompt disappears and immediately reappears, and the game cannot progress.
