Question of the Day!

What was one of the oddest glitches/bugs that you have come across yourself while playing a game?

Yesterday when I was playing Age of Empires 2 HD, the AI decided to produce almost nothing but scorpions, which are basically oversized crossbows. I found this funny because when the developers were making the game originally back in the 90's, they had a similar problem when an AI would do nothing but produce siege rams and obliterate the player's base. Return of the malicious AI? o__O

What about you guys? Talk amongst yourselves down below, and make sure to leave pictures as evidence if you can!
