Crash after updating

Hi,

Just updated the dev kit and I’m getting this error everytime I double click on a blueprint or widget. I can open static meshes and textures.


Fatal error!

For the future always make backups of your project after each day of work (trust me) And always make a backup of your ADK before updating, 3 updates so far have caused it to be useless and broken until fixed, a backup will allow you to continue working til the great devs get a fix out

I got backups on SVN for my mods files, but not for the ADK, no way of taking back an older ADK version ? Im using EpicLauncher

Epic launcher does take some backups, try and locate them and see if that works

You updated ? If yes, no problems ?

I updated with no issues, and epic launcher also gave me the automatic backup so i could load the old test map layout i had if i wanted.
