Sorcerous Reagents Bugged?

Are the reagents meant to stack to only 15 now? If so, that kinda sucks.

I have a chest quickly getting overloaded with stacks of 15 sorcerous reagents.

Do more sorcery? Before the December update you would have had 3 different pouches stacking to 15, 10 and 5 respectively. Seems better this way and normal so.
