If you can't see the unsynced character how do you know it's not happening with other players? Maybe unsynced players are coming up to you asking to give you gold all the time but since you can't see them they just leave and give their gold to other players...

The solution to this is to take the invisible toon and run them way the hell away, then come back. Once you leave the sphere of awareness and come back it all syncs up again.... of course, this is often easier to simply relog.
Because I still have played solo with other people for the past four years, and I never had it happen to my parties of other people. It's easy to spot it, since the character stops moving on my screen but is still actually killing things or healing me. Considering how often it happens to my MB party, it must be something to do with playing off of the same location that makes it more likely to happen.
