Others attaching materia shows up in log, even with "Others Synthesis Messages" turned off.
With some trial and error, it is apparently a "System Message".
Why would this have been marked as "Not A Bug" (http://forum.square-enix.com/ffxiv/t...thesis-message.), it is obviously a bug or a severe overlook! The materia messages are obviously tagged incorrectly and need to be tagged as "Synthesis Messages".
