When units are organized in Division/Brigade level formations the Leader is generally enlisted at the head of other units in Setup Excel sheet.
ex:
StartUnit|7|uni_FRA_Lagrange1
uni_FRA_LightBde12
uni_FRA_LineBde40
uni_FRA_LineBde40
uni_FRA_LineBde40
uni_FRA_FootArty3
EndUnit|uni_FRA_FootArty3
data from Col C of Setup 1813 Excel sheet
Now it happens that's not true for some supporting Leaders/units:
[color="Red"]StartUnit|2|uni_FRA_Med
EndUnit|uni_FRA_Larrey1[/color]
or:
[color="Red"]StartUnit|2|uni_FRA_Pon
EndUnit|uni_FRA_Eble1[/color]
I just noticed enlisted exceptions, although working for most aspects are troublesome in relation to specific event-commands: SelUnqSubUnit, RemoveCuSubUnit,...
I suggest to correct them all to default "Leader on head" way:
[color="RoyalBlue"]StartUnit|2|uni_FRA_Larrey1
EndUnit|uni_FRA_Med
StartUnit|2|uni_FRA_Eble1
EndUnit|uni_FRA_Pon[/color]
...waiting for confirmation!
