After reading through this entire thread, it's time for me to post some strange ones of my own, though some have already stolen my thunder...
I know Austria is a blobby nation, but this is a bit out of hand...
Easy to reproduce but but it made me chuckle nonetheless. I wonder if they're considering Orthodox Judaism as part of the Orthodox Faith?
I know it's been posted, but along those same lines, I had Roma convert as well, which made the Pope very upset!
Maybe not too strange, but it confused me for a bit. It's a Catholic Kahnate with all Sunni provinces. Took a stability hit to honor that alliance...
Another one that has already been posted, but I too had the entire nation of Naxos retreating onto a single cog that is still there, 100 years after the nation itself was long gone. Perhaps more strange than that was that I had a rebel loop on Naxos around the time that the Ottomans' European provinces started revolting to me. I suddenly received notification that Naxos was revolting with no prior knowledge of even owning it. Greek Patriots were besieging it, and every time they won, I received notification that it had fallen, immediately followed by a notification that Greek Patriots had risen in Naxos and that my fortress there was under siege. I thing I tried releasing Naxos, but they wouldn't be released, and I don't even remember what finally ended it... I think I may have finally gotten an army over there to deal with them...
Anyway, back to the screenies...
I may win the prize for most unlikely AI superpower:
Yes that's Malwa.
This is the same game as ridiculous Austria...
Oh, and did I mention that ridiculous Austria and ridiculous Malwa were Allied for a good portion of the game?
(sigh)
Finally, not more than a couple years after I forced Sweden to release Finland, I glance at Asia to see this...
At this point, Finland had about a 2K army of infantry and I don't think Sweden owned those provinces, nor do I think they would have donated them to Finland if they had. I can only assume that religious rebels are to blame. As long as the religious rebels continue to go unpatched, I think there will be no shortage of strange screenshots from IN.
