Baktria - can't build colonies

I've recently reinstalled EBII 2.35, starting a new campaign as Baktria - I've fulfilled the first mission, which should generate three colonists as a reward.

However, I still can't build first level of military colony in neither Baktria (razed the existing one to check if it can be recreated), Marakanda or Oskobara - in the last two I've razed the local colonies and got a choice of either rebuilding them or creating Nagawa Stana (The New Home).

From what I've read it looks like Baktria is not supposed to be able to build nomadic enclaves - could this be the bug preventing me from creating Hellenic colonies, or I just did not receive the colonists?

Apparently I've been too impatient - the colonists appeared few turns after the mission have been completed.
