Yeah, I'm going over it in my head, and re-reading the orswot spec. I think the confusion could be that the spec stores (element, count, actor) where as we _were_ storing (element, [{replica, count}]). It doesn't have to be the whole version vector, but it does need to grow when we merge to encompass concurrent adds. You spotted a good one here. Thanks.

We really need to get some better tests as well, to ensure we catch problems like this.
