When someone in guild levels up, sometimes the notification shows up in the chat window, and sometimes it doesn’t. Same thing happens with guild log in/out notifications. Some show up, some don’t. When I noticed it yesterday, it was only in the General tab, they still showed up in the Guild tab. But today, I noticed there were some that weren’t showing up in either tab.
(edit: this is on the Saga server, I haven’t been on Crom much lately, so I have no idea if it’s happening there as well)
