the turn restriction is 20 on standard speed.This released when it was night for me, but as I don't see it in the changelog, I assume my issue from 4.6.2 persists. So I started a game on marathon yesterday and got two faith ruins on turns ~40 and ~50, allowing me to be the first to found a pantheon with no effort. I seem to remember the faith being blocked until a certain turn to prevent this very thing from hapenning. I later tested in a game with only VP and got a faith ruin on turn 34. If I'm not crazy and such a restriction indeed exists, then it seems the turn number doesn't scale with game speed. Can anyone confirm that this is a bug, so I can report it on GitHub?
I'd assume it'd be 40 or 60 on marathon
