lvl 60 weapon turned into lvl 80
Used an exotic (L60) sigil on my L60 sword.
My L60 sword turned into L80.
This doesn’t seem normal.
It also seems unlikely, as adding sigils doesn’t delete an existing item and replace it. What level character were you on when you applied the upgrade? If you still have it, are you able to take a screenshot to share with us?
Another way to investigate would be to submit the details of who and when (approximately) it happened to Customer Service via a support ticket. There isn’t enough information in the original post for them to follow up.

Well someone had their ascended turn into an exotic through a transmutation charge so something is most definitely going wrong all over the place.
