!Edit!
Well...looks like the patch just disliked my mage...i jumped to my death, ressed and jeah, no durability.
Seemed like an one time only bug but i was missing about 300 spelldmg...and my staffgrafic ^^
Other chars were ok...ah whatever, patches usually produce strange things for an while.
Hi guys
It looks like Blizzard ninja nerfed/changed or at least bugged the boa heirlooms.
I logged on my lvl 73 mage and my first thought was "hmm, something is missing..." my staff was*gone*...better said it had no durability left and was displayed red in my charwindow.
Wasnt a big deal to repair them (~12silver,staff,shoulder and robe, all have now 20/20 durability except trinkets) but still...
Also, I havent found anything about this in the patchnotes thats somewhat annoying.
