You can Merge your DB file with itself

It's not really a bug per-se, but can appreciate the annoyance. We'll see if there's anything further we can change to the next edition of the game to prevent this from happening accidentally, but all I can recommend in the mean time is to keep versions of your file that you can revert to if the main one becomes unusable. 

Apologies I can't offer more.

Yeah not a bug per-se, but I think it is a bug simply because there are no reason to do it, there is no benefit. I managed to delete all the duplicate changes, so I am not upset anymore lol
