Pretty early on in my current Ottoman Empire game I ran across the event popup that allowed the Ottomans to make Byzantium an "Elevated Tributary" but not a vassal (why?), for some pretty good benefits. I said yes and about a month or two later I got another popup saying that "their usefulness as a tributary is at an end..." where I had two choices of releasing them for some prestige or keeping them as a tributary. I didn't need the prestige at that time (I think I had around 70-80) and I didn't think it would be a big deal to keep them on as an EV. Little did I know that keeping them this way meant I could not release them manually, could not really get anything useful out of them other than a few ducats at the end of the year and I could not integrate them later. It's been about 50+ years since that decision and I'm afraid I'm stuck with a pointless tributary that I cannot attack (I'm lookin' at you Constantinople) for fear of the massive stability drop. How do I get around this problem? The City of Splendor is just waiting for me to claim it, but if I could avoid the stability hit I would prefer it. Does anyone know if there's a way for me to make that event I mentioned fire manually or is there a later event (it's currently 1429) that will fix this?
