Thank You! Spartan
The "..chosen a unknow tile for Aryleia..." has been there for awhile.
What happened is, we decided to put the crown princess (by the name of Aryleia) of Geothe Amazon, on the boat at the start of the game, along with the bulk of the Geothe Amazon army.
The RTW/BI engine does not like it at all, interpreting it as an error that an army is located in the water at the start of the game, although there is nothing wrong with it.
Regarding the Red Romans, your 2 cents, is worth a lot more than you put it. So I will definitely heed the advice.
