Cyclone weapon upgrade bug

Hello,

Maybe somebody already alerted on this issue, but I didn’t see it, so I post it here : there is a bug on the cyclone’s upgrade weapon. It should be +2 on each level, not +1, like it really was during 5.0.11 patch, so that damage on level 3 should be 24 and not 21 concerning common attack. Could the balance team council fix it please? Thank you very much!
