Emotes and having the client open 24/7
When the client stays open for X hours the emotes become inaccessible. You can't use them ingame,change, or look at. Error: Sorry! We were unable to access your emotes inventory. Please try again, or contact player support if the problem persists. Error code: EM04
This coincides with the shop "session expired" both fixed with reloading/relog but it's very annoying to do it.
