when converting Kairos to hero I can not attach him to my army. The info box shows only the name, text (for generic tzeentch cultists) and upkeep, nothing else.

steps to reproduce:
- play as changeling
- confederate kairos via console command
- convert kairos to hero
- teleport to changeling army
- try to attach to changeling army
-> "two arrows" symbol for attaching doesnt show up and cant interact with army
-> cant interact with any settlements either

Using the "Allegiance of the Damned: Chaos Confederation" Mod I confederated Skarbrand, Nkari, Kugath and Kairos.
-> Issue persists only with kairos, the others work as expected.
