I try a little league with a lot of AI (5 out of 6) - wanna try some things to see how it works, with a round-robin competition.
I played the first game then proceeded to validate all game of round 1, game by game.
My players ended with no SPPs, my Yeti, supposed to be injured for the next game, is healthy, no gold gain. Same for my IA opponent. I noticed that players have their stats (TD, MVP, CS) into their historic data.
The other AI teams (which play against each other in full AI matches) have their SPPs.
