Guild Wars 2

Just used this to create some of the choosable boosters, but they delete the booster on use, and give nothing.

Using the powder on 4 boosters to give 4 choosable, then selected each type of choosable booster, none of them gave a booster back and just removed the item all together.

Nevermind, apparently these are instantly applied to your character without any real warning, this was not the impression I was given but, I guess it is just an annoyance and not a bug.
