Potion of Unlife Awareness no longer stacks?
 

Logged in today to find my stack of 8 potions (the IVU ones) poofed into a single pot. It didn't have the number next to the icon to signify that it could be stacked. I didn't see this in the patch notes, and it's lame to just have 8 of them poof on me like that.

Was this intentional?

You shouldn't have been exploiting stacking ivu pots like that you cheater!!!

Just kidding, I ate a lot of 20 stacks turned single on the previous nerf, was wondering why they didn't catch ivu pots...

So I guess that's a "yes" to whether it was intentional. Oh well.
