It's probably the fact that since 2.0.1/2.0.2/2.0.3 (not sure which) there is a potential in retinues.
So it used to be somewhat like:
Code:
RETTYPE_CUL_En1 =
{
first_type = 1
first_amount = 100
second_type = 5
second_amount = 200
culture = english
culture = welsh
culture = cornish
modifier = {
heavy_infantry_offensive = 0.1
archers_offensive = 0.3
}
}
and currently it's:
Code:
RETTYPE_CUL_En1 =
{
first_type = 1
first_amount = 100
second_type = 5
second_amount = 200
[COLOR="#FF0000"] potential = {
OR = {
culture = english
culture = welsh
culture = cornish
}
}[/COLOR]
modifier = {
heavy_infantry_offensive = 0.1
archers_offensive = 0.3
}
}
Maybe after changing this something is mentioned differently and hence it was trigger on certain conditions in which it is not triggering now. Whether it is intentional or just a faulty line inserted during patching is not in my knowledge.
Edit: So maybe for prussian it maybe used to be an OR (culture is prussian or german) and is now wrongly an AND (prussian and german) which breaks it completely.
Edit2: My dev friends would like to exactly know which retinue it exactly is and when it should (and now isn't) be available, so it can be fixed. That is, IF the problem is in ck2+ itself.
At least some prussian retinues seem to work.
