I've over the years always wonder why I couldn't merge the 1st Dragoons unit (that's included in the starting army for the Americans) with other Dragoons, unless the 1st Dragoon is first disbandoned then recruited in-game, especially after a battle.
Not long ago I found out why I couldn't merge the 1st Dragoons with other Dragoons, so I took two pictures from vanilla, ETF, and finally TAR.
Vanilla - 1st Dragoons vs Dragoons
ETF - 1st Dragoons vs Dragoons
TAR - 1st Dragoons vs Dragoons
Both ETF and TAR have this unit bug and I think DME might have this unit bug too, but I'm not entirely sure about that. Can anyone confirm that for DME?
I also know a lot of people are using Bran Mac Born's Empire Campaign AI mod and I wonder.
Has anyone notice this unit bug in Bran's Empire Campaign AI mod?
If not then perhaps a patch or an updated Bran's Empire Campaign AI mod is needed to fix the unit bug for the 1st Dragoons in the 3rd chapter in the Road to Independence.
However, I once knew how to change a thing or two in the game files, but that was a few years ago and now I don't remember the necessary steps I need to do to change anything in the Startpos.esf file.
All I know is that this one need OpenOffice, PFM, and maybe EasyEsf or the EasyDb tool.
