The realmlist.wtf is apparently only used for some addon functions. oQueue uses it heavily.

The problem is that some EU and US realm names are shared. There is a US Magtheridon and a EU Magtheridon. However this is not the case for all realms, like yours. There is not a US Mazrigos. So when you log into EU-Mazrigos with a US realmlist setting, the addon throws a error.

You need to configure your realmlist correctly.

Ok, so how do i configure it?

If you are mssing a realmlist file, you can create one. You need to use the appropriate EU values, however unfortunately I don't know what those are other than using eu.logon.worldofwarcraft.com for the realmlist variable.

You may want to try contacting blizzard customer support and asking them how to properly configure your realm list. Or post on the support forums on Battle.net.

Ok, thanks.. I probabbly wont because im kinda lazy :P Thank you for the support.

you might also want to edit your wow/wtf/config.wtf file and replace enUS with enGB

I did, but I still got the same error.
