When warping to Azria, your stats are transmogrified to be impossibly high. Though the stats are hollow, as you still do the same amount of damage, and have the same amount of HP unless you level while glitched.
1HKO Glitch; Seems to only happen after classing up the second time. It will affect all of your characters for a time. It can be remedied by exiting your client completely a few times.
Ghost gathering pets; When warping from anywhere, if you had a pet, and turned it off during the warp, your pet will still be active when you get to where you warped. They'll pick up random items.
Random Items; When standing in front of the Bobos and Luda, you will randomly recieve items ranging from a Battle Shield to Silver Swords of Silver.
Randomly Die; I was walking in Flarine once, and just fell down dead. :V
Egg Vanishes after being hatched; Happend to me. I didn't get a pet when I relogged.
