Guild Wars 2

9/10 logins I encounter the following errors;
Guild interface shows me as only person in guild (Not the only person “online” in guild, just only person in guild)
Get invited to party, accept, shows I am not in party (Can still see party chat)
^Can not join party dungeons due to this.
Other friend/guild errors related to this. Does rather interfere with my gameplay progress. Expect compensation :B jk

C:\Users\<username>\Documents\Guild Wars 2\local.dat <- delete this file. Reload your client.
Note: This will cause some of your graphics settings to revert. But no trouble to go in and fix them up.
