This happened in their screenshots when the glamour system was debuted. They had a mage (think it was Yoshi-P's lalafell) wearing two of the Allagan Rings of Casting and people made a big hubbub. It's just how it is on the testing server, no need to get aggressive. I'm just amused they make that "oops" again.

Wow, actually found the picture (pre-2.2 mind you). Even if you can't read the Japanese, pretty sure you can see that the rings have the exact same text.
