Hi!
I play a game vs one of my friends (tien chi) and an AI (ermor). It EA. Two things happened which i have no clue how:
1) suddenly a large tien chi army appeared in the middle of my empire (in a swamp), with heavy infantry and archers.
2) emror somehow attacked two of my farther provinces with madmen and madones.
(yes, my friend tries to keep his secret... I guess he is very afraid to lose any advantage ..
)
