As mentioned in the title, Fishing boats are benefiting from Yuan’s 15% movement speed (stacking multiplicatively with the tech Drift Nets so with both bonuses the fishing boat ends up having a movement speed of 1.9 cell/s ) even though the Yuan bonus mentions only Villagers, Imperial Officers and Military units. Transport ships and trade ships also benefit from the Yuan Dynasty.
In a previous bug report I reported only for trade ships as I was not aware of the case of fishing and transport ships.
