Next release will have a fix for most of the missing names, thanks for reporting. However, I opened your save with Invictus, Navigable Rivers and compatibility patch, and there is a province with missing localization. Is it the same for you? If not, how is it named?

no, it wasn't like that in my game, probably happened some time during upload of the save? Other than that, it looks right.
Also I decided to do one more campaign for imperator while I wait for the fix, and I just about got it to the date I wanted to convert from (1308 AUC, or 555 AD, which was the year of Justinian's near-total reunification of the roman empire.) when game crashed, and I didn't feel like loading it back up to run the last 8 years...
*Save would be here, if I could put it here*
In this save, I decided to take control of Bactria (removing their vassalization) but only for the lifespan of one monarch, Sophytes I, and then observe. I was able to play Maurya, Dravida, and the Seleucids off of eachother, assasinating several key persians, and getting one loyal to me on the throne, leading to an alliance with my former enemy. The AI, from this point, managed to defeat the mauryans with the help of Dravida and Seleucids, then turned on both, and managed to win out, forming the Indian Empire. Also Rome had a civil war and the Republic won, and then they kind of chilled for the rest of the game. Carthage went dictatorship, Lysimachus and Ptolemy did typical Diadochi things, and Lemovicia... used to be democratic republic, and then got pummeled by all of its southern neighbors.
Turns out in late-game, if you have too many big blobs, the AI will mostly just chill out and stop declaring wars. At one point, I went AFK and let the game run for like 200 years, and AI was still at a stalemate. I think this might be some kind of anti-lag, since when a bunch of blobby nations do go to war, the game slows to a crawl. Also, for whatever reason, I had a lot of instances where the AI would declare a war against a weaker neighbor, then immediately surrender to them and give them a bunch of land. Which is a serious bug.
