Do you collect the coins at the end of the Gypsy player's turn, or at the end of the game round?
The Gypsies ability states:
At the start of your turn, you place coins in each Region your Gypsies occupy. At the end of the Gypsies turn, collect all coins in those Regions that you don't occupy and return the remaining coins if any to the Victory stash.
The rules state a turn ends after troop redeployment and Victory coin scoring.
Gypsies essentially allows you to score a Region for one additional turn after abandoning it, because Gypsies are always on the move.
While it is worded a bit strangely, it happens at the end of the gypsy player's turn, just like all other scoring.
