What's the single most rage inducing thing you experienced in the game?

Mine happened yesterday. I was doing a quest that involved catching a largemouth bass to bring to Demetrius. I was able to catch it incredibly fast, I felt so lucky. Having the bass selected, I ran right over to his house, right clicked on the door to get inside, and JUST IN THE SAME SECOND Sebastian left the house and I accidentally gifted the fish to him. I stared at the screen for a good minute trying to process what just happened before I cursed at Seb for another five minutes. Like this guy hangs around his room all the time and the ONE TIME he decides to go outside it HAS to be in the same second I want to get inside??? Really???
