My tribute AI works- half the time. Sometimes, it will just stop tributing when requested. And it's not a definite time. Sometimes, it's early in the game. Sometimes, it's later.
The thing has a built-in cheat, so I know it's not ever running out of resources. There are resources, working AI tribute-when-taunted lines, the computer player doesn't resign.... what gives?
Uuuunnnnngggggg..... brains...
