Now it’s just a matter of the add-in not communicating reliably. At the moment it’s responsive, but I’ll keep monitoring.
Hmmmmmm. Did an orderly save and shutdown of the sheet and Excel last night only to reopen the file today and find that the corruption had returned. Had to do the Find/Replace all over again to recover it.
Very strange, I’ll make some notes on this and try to get a coherent ticket to the addin team at microsoft to report on the failure to properly link the addin.
At least it’s good that it’s consistent so you can do a replace all. But understandably frustrating.
You can send me a copy via Discord (username: Hundasupa, I’m also always posting in #spreadsheets on the eve discord) I’d try inspecting the excel workbook metadata and compare it to my own sheets so I can maybe spot why it does this, maybe. 
Hey Hundasuupa,
{“error”:“invalid_scope”,“error_description”:“The requested ‘esi-characterstats.read.v1’ scope is not valid.”} since today downtime ^^
Could you take a look please ?
Already reload the Add-in, uninstall etc
Thanks o7
The update was pushed very soon after the scope change, but it was in a hard spot to update, could be very cached on the client side.
Hopefully it’s resolved now. 
Ctrl+F5 inside the addin window can help if it still persist, or a clean web-addin reload via settings.
