What happened to all my conditionals?

My conditionals have all re-written themselves. What were different conditionals have now become duplicates of each other. 

I think I'm learning there's a limit to what your conditionals can handle. I've created a form with a lot of conditions and its not as stable as it needs to be. I've lost huge amounts of conditionals in the past, they've just disappeared and now, there are several duplicates of various conditionals. My thought is, in creating these conditions, I duplicated several of them and edited them, and now, weeks later, they've reverted to their old status. I dunno. I hope that reverting to an older version restores them. Otherwise, I'll be re-working them for hours.

Yes, you can check the history of your form and see the changes that were made on it.

You can restore your form to a previous version, where it was working as you need, so you will not need to create all your conditions again.
