Turns out this has nothing to do with sieges. I have narrowed it down to either a network issue (tcp/ip) or the database going to sleep if not used for a while – or something similar to that. Can anyone confirm that they were online when the weird behaviour started? Not just the last time, any time it has happened. And by online I don’t mean log in while it is happening, but while you are actively doing things, suddenly no soulshots etc.
