The game is randomly not registering achievements even though they are completed. Seems to happen more in older zones.
Just wanted to second this. I noticed this with the "Seneschal Slayer" achievement for Mistmoore Catacombs and Wreckrock Ruiner in Klak'Anon.
Seconding this, I just killed the Seneschal in Mistmoore Catacombs twice and did not get the update for the achievement. My character is lvl 70, on the Antonia Bayle server. It just happened less than 5 minutes ago.
Can anyone affected PM me your character name, server name, and what achievements you are seeing the issue on?
Here's a forum post with one that was confirmed. Not sure if we have to bug every achievement as some are hidden and would most likely get missed. Confirmed - Seneschal Slayer Achievement not Updating after kill | EverQuest 2 Forums (daybreakgames.com)
Also sort of related to your post. My guild dinged (finally) level 350 and there was no message, no world message, and nothing on the event page.
Ya I think so, but I am the guild leader and I have all that turned on. At least level 50 and above should show announcements. Anything below level 50 is easy peasy stuff and goes so fast I didn't feel a need to broadcast them.
