Game Mode blueprint keeps breaking

Development Programming & Scripting

When I make a brand new game mode this is what I see:

Then I don’t do anything, just Ctrl+S in the editor.
I reopen game mode and this is what I see:

If I duplicate the game mode nothing shows up just like the original.
But if I create a child game mode, it’s operating normally, until I save it of course.

Any fix for this? Is this a bug at all? Am I just stupid?

Edit: Forgot to add that restarting the engine doesn’t solve this.

Edit2: This happens only in projects that have been created in a template. Any game mode bp, including the one provided with the template breaks like that. Even without editing anything (just create new bp project from template) this happens.

Hi ,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this on my end?
  • Have you tried using the “Reset Layout” option found within the Window menu?
  • Are there any other blueprint types you are experiencing this with or does it only occur in game mode blueprints?

Happens on any new project in a 4.9.2 Including blank.

Honestly I don’t know how to replicate it, all I have to do is make a new project, create a game mode BP and save all. After that the BP is broken.

On the other hand the Reset Layout option does fix the problem and prevents it happening in the future.

Thank you.

I am happy to hear this helped address your concern. For now, I will mark this as answered for tracking purposes. If you experience this again please post here so I can look further into this on our end.

Just as a sidenote, it might be possible that by default now there’s only 2 events available upon creation (begin and tick), compared to the 3 that used to occupy the area. Maybe that’s what was caused it. I did some more testing and now I can’t replicate the problem.

Either way, Reset Layout fixed the problem for future projects, and I was way too quick to fix the broken ones, so I failed to investigate what was causing it. I’m sorry but I think this bug may have been caused by updating the engine version, and after resetting the layout I don’t believe it will ever resurface again. Thanks for your time man.
