This issue has persisted for some time. I remember trying to muck around and change the requirements myself, but removing the dragon conditions caused all matter of issues.
Thank you! Looks like it is the kowtow, and I might've found the root cause (bad scripted_trigger) - which has been committed to the repo. Please mind that this means we've likely had no-one test it (and it'll be entirely vanilla anyway).
If they had unique COAs in the past, then not too sure - otherwise likely because noone has made COAs for those titles. We're totally open to any contributions, so if you have any favourite characters or dynasties, feel free to make whatever and we'll add it!
