No Longer Working

Is it true that this plugin isn’t being updated or supported anymore? It’s crucial to our team and how we function. Please say it isn’t so! I have a couple problems that I would love some help with:

1. The revisionize option is no longer available on some of our posts and I can’t figure out why. Is there a limit as to how many times a post can be revisionized? Can I change that limit? Why does it stop working?

2. When some revisionized posts publish, they completely vanish. I find them in the drafts, thankfully, but the url gets messed up and it’s not working well. This is happening randomly.

3. Is there an alternative to this plugin is it really isn’t going to be updated or supported anymore? I need something that will duplicate a post and publish it on top of the current copy while keeping the same url.
