Women’s championship and the invasion

I know you must love Invasion questions because why not, and I recall how just before the invasion there was the debacle with Chyna who was then Women’s champion. That led to her and the championship going into limbo. However, checking the history, the title wasn’t officially vacated until November, so theoretically China was champion throughout the invasion.

My question is, was there ever an explanation for the disappearance of chyna and the title? Did WWE have any plans for using the women’s title during the invasion but never pursued it? They clearly had no problem throwing torrid Wilson and Stacy Keibler into matches (later adding Ivory to improve the quality of the WCW women), so I imagine they COULD have used the women’s title as one of the many belts to swap around.

Oh, and was there a reason that Ivory joined WCW? Or was it just because? At least Molly holly had a history with the promotion…
