Game Mechanics: Charges lost to OOR?

[Brut]

Tried to google this to find out if it was so live, but... hard to find. So figured would just ask.

Tried to pull stuff in KK and root a named with Wooly Nets. Target is out of range (he decided not to come up, think it was ravenous piranha.. thought he was some named mob with great lewt! =p). Item is out of charges after 2 clicks. So it ate my charges despite not actually casting the spell. =(

Working as intended?
