I've fixed a couple of bugs and typos for the hotfix, whenever that is.
One fix I think people will be happy about: I've tested and pushed a fix for the longstanding "opener not counted in policy count" issue. Opening a policy branch will now correctly display (for example) "1 tradition", getting the first policy "2 tradition", and so on.
Additionally, I've tweaked the diplo AI to not apply a diplo penalty when one player has 0 policy branches unlocked and the other has 1 policy branch unlocked (so higher difficulty players will not get more AI aggression right off the bat due to a lack of culture).
This fix also remedies a small visual bug in this version where the "similar/divergent Social Policies" modifier is displayed incorrectly.
