If you use the chimaera wings then while it's casting you switch to another item in your bar it replace that item with chimaera wings equal to their value.
I used chimaera wing, switched to chicken (x64) and ate one (now 63) then chimaera wing teleported me and i had then the original chimaera wings + 63 brand new chimaera wings and no chicken anymore! :O
That sounds pretty bad, I'll have a look.
Haha, it was a pretty funny bug though :)
Fixed bug with ChimaeraWings not taking Wings from a players inventor…
Updating to the latest dev build will resolve this issue for your server. (I recommend doing so, I'd imagine players could get really mad/sad when they "magically convert" a stack of diamonds into a stack of ChimaeraWings..)
