Did you ever figure out how to get rid of the red promotion text mate? Got the same issue with my AFL/VFL league structure. AFL reserve teams in the VFL, 0 promotions, yet that annoying red text is there
EDIT: I think i've managed to work out how to remove the red "cannot be promoted" text
Instead of having my division as level 2 in the basic editor, i created it in the "reserve" structure section, converted to advanced rules, then converted that division to Level 2 by changing division type and adding them to the comp section on nation page. This has removed the cannot be promoted text and all seems to be working fine. Just run a 25 year in game test and everything is working
Hope this makes sense
