Corrupted blueprint won't let me fix it

Hello! I have a corrupted blueprint, but i can’t do anything about it because it crashes my editor when i try and run it, so i can’t open the blueprint editor because that makes it run the blueprint, what can i do??!!
I really don’t want to have to delete it!

If you’re not using any form of version control, you may have just learned its importance the hard way. Set something up with Git to avoid this in the future. Ideally, if you had version control, you could step back to a version where the Blueprint is working, copy the asset somewhere on your computer, return to your recent version, replace the corrupted one with the working one, and then redo any work that may be missing. It’s better than having to delete it completely.

Hi there,

A backup is automatically created (so long as you have autosave enabled) so you can take an earlier version of that asset and overwrite the one causing the crash.

Open up your project’s folder in Windows Explorer, and navigate to:

YourProjectName\Saved\Backup

And find an earlier version of the asset (go by date/time), then right click and choose copy on it. Next you need to find the problem asset in your Content folder and delete it (or make a backup), then paste in the file from the Saved folder and rename it to be the same as the deleted asset.

With that done you should be able to open it up again, if not you might need to find an even earlier version in the Saved folder. Some of your changes will be lost, but it should save you a bit of work.

Hope that helps!

thanks for the helpfull answer
