In Hot Seat when two human players are in one team the following were observed:
1 - Era ends countdown notification pops up only for the first player from the team, the other player don't get the countdown
2 - If the team's second player involved in attack, the attack details (blue frame at middle of screen) appears for the first player, instead of the second one.
3 - The beginning of the turn when "save game" and "start turn" options are available, if opens the menu from the icon of top right corner, after choose resume game, after that choose "start turn" -> keyboard arrows don't scroll the screen. Do it again (open main menu, resume game) and the arrow keys are working again.
+1 - Not Multiplayer specific -> Matterhorn bonus (Alpine training) doesn't apply for the Sumer War Cart, but should applies for all land combat units. (Also would be fine to mark somehow if a unit has natural wonder specific ability)
