Whether you quote a post made before the name change or after the name change, you will see LoyceV2 in your quote by default.
If you have quoted a post before the name change, you will still see the old name even after the name change.
Are you saying that should work differently?
I don't know how the current version of SMF works and how its databases are stored but I think it should be possible to change the name of the quoted user. I'm not a developer but I'm learning coding. I think that the logic of changing the quoted user's name should be something like: If quote author = "Poker Player", replace it with "Free Market Capitalist".
Let's wait and see if PowerGlove can do the magic.
It seems it's working the way I suggested it, and the quotes I saw that made me think otherwise were having the old username because those users had probably changed the username manually. I thought that the quote was fetching the old username automatically instead of the new username, but that isn't the case as it seems.
My bad, guys.
