I do not how to format multiple responses like you did, so I’m gonna respond this way instead:
Q1: I migrated my entire content folder into the new project to make sure no dependencies were lost, it got to 100 percent and crashed when it finished, giving the same error as before. That being said the files did actually migrate into the blank project, but the controller still didn’t appear in the file it should be in.
Q2: So if i were to take a blueprint out of a project, rename it in the file explorer(or in the project files), and put it back in, that would cause issues right?
