I noticed that descr_events in 1.3 has changed to become similiar to BI. It mentions in comments to list factions in descr_strat as emergent.

I did this for parthia and it loaded, but I lost right away since I didn't exist yet.

However, with any other faction it crashes and when you hit end turn. Parthia's provinces are empty rebel cities.

It's entirely possible that the entries' are just leftovers, but I want to make sure since it would be nice if it could work.

Could someone with BI go over how emergent factions work for it? (I don't have it)

Thanks?
