Ok, I've redesigned the way it handles startup/shutdown to be a lot more robust, so it should no longer leave left-over bits of the plugin running from the previous login- i.e. no more duplicate xp messages. There was a few other things duplicated as well, although not immediately noticable- for example, it was highlighting attacking creatures on the radar multiple times, but you wouldn't notice that, as the duplicate blips were just on top of each other.
