I buy the cripple mod, apply it to my comp bow, and now I have a Comp bow of fortitude with no mod, not even the old poison mod that was once on it. Thinking this was maybe just a one time bug and since crip mods are cheap as dirt I buy another one from someone in Kaineng, do it again...and the same results, I'm simply left with a Comp bow of fortitude with zero string mod. WTF Anet...you owe me 1k!!
