Green Gloop Quest Broken?

So I recently created a new assassin, and I got to the green gloop quest and Yodbon want's 5 glass bottles. I'm not sure how to get them. The mobs around Almuj drop Water Bottles, but they cannot be drank, therefore no glass bottles (I also tried turning it in the 5 water bottles, but alas no success.) Potions are insta-drink now, and they just become removed from your inventory when the last portion of it is used. No glass bottles made. I might just be blind, but this seems impossible to complete.

 

Zombies at the emerald trail drop empty glass bottles, might take a while just need luck

 

Hmm, thank you, I didn't know that. That seems a little too far away from Almuj though x)

 

Yeah but that's why we have scrolls to scroll our way across the map

 

In ragni is a water merchant

 

The water merchant doesn't help. Right at the entrance of Nivla Forest, the zombies drop lots of bottles.
