Miscellaneous: Sow Potion casting level incorrect

[bulbousaur]

From what I recall on live, a player consuming a sow potion received a sow of the level of the potion maker, that is if a 50 Shaman made the potion, you get a level 50 sow with the speed and duration as if that shaman had cast the spell on you.

I have a level one spell mule that I gave some potions to. When he uses a sow potion, it wears off in ~ one minute. It's apparently casting it as if a level one shaman cast the spell? Thanks.
