Two characters with the same name (one ded), can't see achievements

Hi,
I initially made a character as a joke (name is "AmeribadsLOL"), then remade it and started playing it sorta seriously.
After noticing that the achievements page for that character was blank, I looked on the forums for a fix, and found this: https://recursion.tk/showthread.php?...ts-not-to-show
If I understand it correctly, there are two entries for that character, and it's automatically showing the older one. Could you delete the older character from your database?
