Is this documentation out of date?

Is this tutorial out of date? I’m getting a lot of unusual errors (See screen cap).

Sorry I forgot to link to the tutorial haha :expressionless:

One thing that really threw me off when I first started programming in UE4: The error list is generally a bunch of gibberish. You actually need to look at the output log to find the error.

when you are debugging in Visual Studio, you might see a hundred errors. The one you want to focus on is the very first one.

I mean I figured it out. I was just asking if the documentation was out of date b/c coding the tutorials as they were resulted in these errors. Most of the fixes so far where adding header files or adding PrimaryActorTick.bCanEvertick = true. Neither of which are stated in these tutorials. I did find these solutions in other documentation/forums. It’s just this particular document seems like it needs an update.
