This is the string the app gave me
Thanks for the report, we’ll take a look and fix what is causing this error, though it might not be until Monday that we can update the site.
In the meantime, you can avoid the error though – I believe it is running into some unexpected case due to an incomplete hero talent tree.
On the “Set Up Best in Bags” tab, under Step 1, Pick Talents, choose one of the auto-update options. I would suggest starting with “Last seen talents for this spec”. When you choose that option it will automatically update your talents to the last ones we saw in-game on that spec, and then each time you import it will update your talents as well.
Using your last-seen talents (a full Totemic build rather than your partial Stormbringer build), it does not run into this error. You could also manually fill out the Stormbringer tree to avoid the error for now as well.
