I was learning the Blueprint system by following the TeslaDev videos and I was using the Sedan in place of the skeletal mesh for a gun (as I didn’t have a gun). Anyways I got everything set up and it look pretty hilarious but then I tried to run the game and it crashed. Now whenever I try and open my project file it crashes instead of opening. I don’t know how to salvage all my blueprints I worked on in my other project file so I’m fairly bummed. Is there a good way to import the blueprints I had saved from my other project into a new project without being able to open that old project? I don’t want to lose my progress.
Hi CJFerguson,
What version of the editor were you using? Additionally can you post your crash logs here? These can be found at \Unreal Projects\PROJECTNAME\saved\logs. If you go into the filepath \PROJECTNAME\content\ you should be able to pull the blueprints out of the contents folder. If you do this, try pulling out the sedan blueprint then re-open the projec to see if it will open.
Edit: I removed the sedan.uasset from the content\blueprints folder and now the file is opening correctly. Is there any way to get that blueprint fixed and back into my working properly or do I need to start over with it?
I’m running 4.6.1. I just opened the most recently altered text file. Tell me if this doesn’t look right and I’ll try and get a different one. I’m not very versed in Engines or code yet. I will try to pull the sedan blueprint.

If you go into your projectname\saved\backup\ filepath, you should be able to get a working copy of the sedan blueprint and move it into the contents\foldername\ filepath to replace the broken copy. Try doing this and see if it will open. Can you also post a screenshot of the blueprint that is using the sedan? Are these referencing each other through a single function (cast to the sedan, then cast back to the player, for instance)?
