Not really a "bug" per se but if you have, for example, the Hardened Wing-Membrane effect on a pair of armguards, and then also enable say, for example, The 'Fyakki Damage I' title, EVERY SINGLE time you attack or do anything damaging your chat log will have a message like the following: "Attack already has keyword (2398) so event Iron Ringmail Armguards keyword (1721) will not be applied."

It's super spammy and kind've annoying - also unclear that such effects apparently don't stack?
