Thanks for the feedback. I've just uploaded v0.89, which improves the AI logic for negotiating peace a little bit. From the GitHub log: "... in situations when the AI wants peace, but thinks that the human player wants peace more badly and therefore demands reparations (gold, tech, cities) ..., the AI now agrees to fewer reparations after a while if the human doesn't have enough to give." Can't say if this fixes the problem with the stalemate war in your game, but there certainly was a problem. I could look into the other issues (dogpiling, city attack courage, assistance for friends) if you happen to still have a savegame.
