Welcome to the Community 
I’m sorry to hear you’re also experiencing this issue!
I do see that we have an open feature request to be add the ability to roll back the board to a particular time, so I would recommend upvoting this so that it can gain more support.
You can find this here: Undo/ Restore Board to a certain time - #3 by andrewalmand
This will help our product teams to better understand the demand and need for this addition to the platform.
I know this isn’t a solution, but I do hope it might help to get this resolved in the long term for you.
Best,
Dani
