Unable to repliate, it may be a specific case, have added additional logging as detailed below. Likely a cause of the combat logging script, this has been ammended in the development build.
You may recieve a "You combat logged" report sometimes, don't worry about it if you didn't combat log. I'm using some logging to find specific cases of where this seems to happen when it shouldn't.
You should no longer trigger this by reporting a false positive.
