It's possible that the Order spread to thier lands first and they immediately converted. The AI has a bad habit of converting to the first religion that spreads to thier lands.
In a recent game, Perpentach (as Balseraphs obviously) converted to RoK when that spread to his lands, but a while later he founded AV and converted to that. So despite the brief time as neutral, he went back to evil.
No idea why an evil civ like the Doviello would convert to the Order. Just out of curiosity, how many other religions are founded in the game that you mentioned.
If I remember right, they all had. But, like I said, I was playing multiple continents and it ended up that pretty much every Civ had their own continent. I know I had founded Cthulhu Overlords...I mean Octopus Overlords as well as AV and Council of Esus. I'm pretty sure that Elohim had researched Order and Empyian and Khazad had founded RoK. Actually I'm surprised that they got Order instead of RoK since Khazad's continent was closer than Elohim and even the Elves' continent was closer with their WotF
