The data import from Game into the web interface is not reading artifact weapons correctly.
For example, when I import, it reads my artifact weapon as level 750 and not 934, as it is in game.
Did some testing
Zygor is also reading the artifact weapon as 750 and not 934
Pawn is also reading the artifact weapon as 750 and not 934.
If you import from the armory, the ilvls are correct.
It’s a Wow-side issue.
