Bulk Undo for Trello

[Ace C_]

I tried using a power-up so i could use a free Gantt chart (since i do not have trello pro). I ended up changing every single due date in the entire board... and have no clue how to fix it. Is there anyone in the vast internet of Atlassian who can help me solve this?

Thank you in advance, even if i dont get this fixed.  :)

Sadly I don't think there is a way to correct this.  

I don't know just how many cards there are but if you changed them all once, I guess you can change them all back one by one.   If you look in the activity log on the card, you will be able to see the original date.

One for the future, there are power-ups that can rescue from this kind of thing...

The Rewind powerup is worth checking out
