Possible to edit a blueprint outside of the editor?
While programming a blueprint I made a mistake and included some sort of loop that crashes unreal every time I open it. I am able to open the project, but I can't load any levels that have the blueprint in it, and I can't edit the blueprint to remove the destructive pieces. Is it possible to remove pieces of a blueprint from outside the editor? I Know which node it is I just can't remove it currently. If I can't edit blueprints outside the editor is there anyway to fix this problem?

Sanity check 1: Are you using version control? If so, you may just want to revert to an earlier commit.
Sanity check 2: Do you make periodic backups? If so, you may just want to revert to an earlier backup.
If sanity has failed us today, then here's what you do: ;-)

What happens when you go into a level, that does not have the blueprint? If I remember correctly, you should be able to open the Blueprint in a level that doesn't have the blueprint (heck make a new level, and switch to it).
you can also rename the blueprint in the content folder, give it a new file extension, UE4 editor looks for the "uasset", change that, and it will not be loaded. This will allow you to create a new level, in which you know the blueprint is not located. Then close the UE4 editor, rename the blueprint back to have a file extension of "uasset", reopen the editor, and attempt to edit at that time.
