I've had some (when I tried to sell an item for 0 gold to someone, but that was a while ago). Give the info of what you're doing when it happens so Tom can address it if it needs addressing
Loading the selling page.
Maybe you missed that you need to go to the account page now and log in first? Or maybe you have cookies disabled?
Does this one actually count as a success? Looks like they failed most of it. Also, one of the characters died, then continued to lose items as the quest continued.http://shopkeeper.lemuria.org/api/quests/114/log
Now it's giving me a 403 error. The login page still says it has my shop key set though. No plugins that are blocking the site or cookies from the site. Weird.
That is very, very strange. Which browser do you use? Can you check which cookies it has stored for the shopkeeper.lemuria.org domain?
It might be an issue with mobile browsers, as I've tried on both Chrome and Firefox for Android, but both give me the error. Not sure I can see exactly which cookies were set.
Have you also "checked" the shop key? I had mine set but not checked which caused issues.
