Did Unreal just corrupted my project?

[Slydex44]

A few days ago I started a new UE project and during today’s work session it just broke. I was just moving nodes and testing changes and once I clicked the play button another time I noticed that player doesn’t move and nothing else works except mouse input. I tapped escape and saw this in the message log:

Thousands of “Accessed None” messages and all of them are related to Character movement and Capsule component. I literally don’t understand what the hell happened and how to fix it.

Any ideas?

/Update

I’m using GitHub for version control so I created a brunch from yesterday’s commit and started checking the difference and found some in BP hierarchy:

Yesterday’s version:

Today’s version:

Capsule component became Root component (who knows how did that happen). Also, there are 0 properties in the details panel when I select Root component or Character movement in today’s version, but I see everything in yesterday’s. Maybe I clicked somewhere accidentally while switching windows, well, would be great to know what action led to this.

The accessed none is because there’s a mistake in your blue print

It’s been covered literally hundreds of times on here.

The rest, I think, is a bug. I’ve seen others reporting it. I’m afraid I’m not sure what the solution to that is ( I will take a look )

Well yeah, I agree that Accecced none is a common thing but I re-checked every inch of a blueprint and found 0 mistakes. Btw I didn’t even work with character movement or capsule component nodes when that happened.

Anyway, I restored previous version of the project and moved all changes to it, works perfectly.

But still, interesting what’s the reason behind this situation. Maybe really it’s just an UE5 bug?

I’ve seen the missing details for a component quite a lot, so I’m assuming it’s a ‘feature’…
