http://imgur.com/3PGLQMsI gave the AI the same deck I was using, which included Tubular Bells, and it apparently decided discarding Bells was better than getting +1 Facilities. I can understand if the AI just has some simple "if x chance in y, discard randomly instead of playing a card", but the player is generally going to expect that an opponent will act in it's own self-interest, even if it isn't the best at doing so. If they didn't understand how that card or interacting cards worked perfectly, it would probably be very confusing instead of just a little confusing.
(Or
Feature Request: Give a selector in the AI Games section for how good the AI is; simultaneously making it transparent to the player that they're playing the newbie AI, and allowing them to pick a better one if they like.
Bonus FR: Allow player to select a default AI so good players don't have to keep switching it off the default almost every time they want an AI game.)
