Whenever I try to buy an item from a user shop it goes "Item doesn't exist!". This only started happening when I was finishing up my Saggi quests.

Edit: I'm using Chrome by the way. I'll see if it happens on Firefox too.

Update: Still bugged on Chrome, but working on Firefox.

Feel free to add your report here: [topic not found]

When this happens, try doing a hard refresh as well.
