-I have gotten a bug with my chains, sometimes during long boss fights where I have to FD 5+ times my chains get bugged and don't pop when they should.  I even tested it with my auto crit chain forcer ability (and it didn't miss), the only way I can fix it is to FD and meditate real quick.

-There is also a bug dealing with damage shields (in my case in particular with crafted gear) where it will proc on the mob, seconds after it attacks you knocking you out of a successful FD.

- Soaring Leap sometimes gets bugged and it is like you have parachute on even when you don't, so you just float to the ground mid leap.  Chunking fixes this usually, and I rarely see it in APW so not sure what causes it.

- for some reason tdragon stance sometimes sticks when I change to storm dragon so I get both effects.

I have petitioned all these, and talked with GM's about them and so far they have just said they are not intended and would submit it for me, but I thought I might as well add them here. 

its fixed in gu4, and yeah it blows ive had it a lot, i thought at first it was a bug with rune songs blocking it but its not.
