Original domain not working with domain mapping

Hello.

The strangest issue has occured on one of the blogs in my network:

liverpool.fotbollsbloggar.nu has the mapped domain totaalliverpool.com. Everything has worked fine up until today (or atleast I have first been notified about this today). Note that this was before I updated the domain mapping plugin so it has nothing to do with the update.

liverpool.fotbollsbloggar.nu seems to have the configuration that it should have, but it seems to point to the content of spake.sportbloggar.nu (on same network with multi-domain). However, this domain should redirect to totaalliverpool.com and nothing else.

Anyone have any suggestions? I have tried to clear cache (QuickCache), re-configured domain mapping and repairing the DB.
