My Project After Updating 4.7.4... Doomed?

Q: When you say your project isn’t working, what do you mean, exactly?

Well, something like this,

  • camera of my player is moved at zero location.
  • controllers not working
  • no HUD
  • every time I open my project there is this compile error at moment’s notice

Q: Does it not Play?
→ It runs in PIE but just as i mentioned about state of my work above…

Q: Does it crash at some point?
→ No

Q: What did you do in new project before closing and reopening it?
–>Just normal save, then close, then opened it again. then same thing happened to my new project.

Any screenshots or additional information that could help us reproduce this would be tremendously helpful.
–>I just reverted back to 4.7.3, there’s no way i’m going back to 4.7.4 after what happened :S
