Are certain units excluded from the free upkeep slots of city walls?

[Conan's Might]

Hi guys,

Playing as the Roman Empire on early campaign with the mod complication and one settlement type active...Its brilliant actually enjoy it more then the two type system.

Anyhow I've recruited the heavy spear units that take 3 turns to recruit ..not sure of there name. But they fail to become free upkeep.. the walls Constantinople allow for 4 free unit slots. After recruiting 2 separate units neither became free upkeep... this was with no other unit in the city except familly members. But when I recruit the sear militia unit they fill straight into the free upkeep slots.

Is it unit that requires more than one turn to recruit cannot go into the free upkeep slots when recruited?

[PerXX]

Generally, professional troops are not free upkeep. Militia and Feudal (and possibly Local, can't remember off the top of my head) will often be free upkeep.
In order to be a Free Upkeep unit, the unit needs to be recruitable in that settlement, as well as having the tag free_upkeep_unit, in the EDU.

Examples:

Halbert Militias will be Free Upkeep in a settlement where they are recruitable, because they have the tag free_upkeep_unit.

Since the Venetian Heavy Infantry doesn't have that tag, they will never be Free Upkeep, regardless if they're placed in a settlement where they can be recruited or not.

If you wish to change this, you can simply add the free_upkeep_unit tag to any unit you wish. Just be sure to back up the EDU before you start editing
