In Northwest passage
bought all the sno cones in fact bought 2 purple. now problem there.
Also bought all the other colors,, the vendor took all my money and I had plenty of inventory room but no cones.... WAH!
Hmm - I had similar problem. My inventory filled up after buying the first two. I checked the quest log and it had not registered those two being purchased, even though they had been in my backpack. I dropped three things on the ground and purchased the other three. No sno cones showed as being completed in the quest. I eat them all, managed to make some more currants and went back to purchase more.
This time I made sure that I had at least 5 empty inventory slots. Purchased all five and got the quest completed.
I was prepared to lose all five sno-cones in completing the quest... but I lost the quoins the sno-cones and didn't get the quest completion until I repeated the exercise a second time.
So annoying.
It was in my to do list If I remember correctly... I may be wrong. I do know it didn't pop up again... I do know I didn't get the Quest completed box and rewards until I went back and bought everything again.
Do you have to buy all 5 sno cones at once? I never have enough money to do that - but whenever I leave Wintry place - the sno cones I bought aren't registered on my quest anymore - it goes back to saying I haven't bought any.
