I have put in checks that I think will avoid this error… I’ll have to give some thought to how to reproduce it and be 100% sure that it won’t happen again though.
You must have an item in your bags/bank somewhere that has a different item link format than I’m expecting, but short of writing some kind of helper to save the item links for every item that you own and sending it to me… there’s no good way for me to figure out which item is causing the problem. So hopefully this tweak will just avoid the problem. After I put out the updated version of the addon in a little bit, give it a try and let me know if the error goes away and all your gear looks correct on the website and in-game (showing the right item levels, etc.).
