When hovering my mouse over items in bags (both Talented and Bagnon/Sell Price per Unit are active) I got following errors:

Thank you for reporting this. I have Bagnon and multiple other addons that modify tooltips, but haven't seen this problem. I'll install Sell Price per Unit later to try to track down where the conflict is.

I'm sorry, I couldn't reproduce this. Could you see if this happens with just Bagnon and Talented? Or just Bagnon, Talented and SellPricePerUnit?

Sorry for wasting your time, I've just noticed I forgot to add Bagnon to an addon manager so my version is grossly outdated. Probably that's the case.

No worries. Happens to all of us.
