I suspect you're either talking about Den-Swe or Kie-Hol, but I'm having trouble naming a bias with regards to either of them.

Kie-Hol isn't just loss aversion because if Italy had gone to Munich, Italy would have grown- but if one assumed a 1/3rd chance of Italy going to Vienna, Munich, and Venice (which ignores the possibility of moving to Trieste), then moving to Hol would have been a 1/3rd gain (counting Italy's gain as negative), whereas moving to Mun returns 0. So perhaps this is "shut up and multiply" or "visibility bias"- only looking at the possibility that Italy would move to Munich, and ignoring the other three spots that would be good to go to?
