Same goes for the Mexican general. The grid positioning need to be adjusted for the new build options.
Yes. The grid layout system cause too many bugs. Have devs thought about extending the grid from 3x6 to 3x8 ? May be a good solution.
This was my proposal to have a dynamic UI that allow more columns for this kind of problem: Proposal: Dynamic UI for units and buildings? - Age of Empires III: DE / III - Discussion - Age of Empires Forum
I used to have this problem with the Nizam Fusilier after you send the card to allow janissaries to build military buildings, but devs removed that ability form Nizams. Still, many units on the game have this problem, so it would be good if something like this can be applied.
