Accessed None error from node
Hi, I'm getting hundreds of accessed none errors in my chunk creator but I don't really understand why or what they do? They're all pointing towards the set entrance piece which sets one of the 4 sections in my chunk. Any help would be great.

This is more often than not caused by a null reference. If you're trying to access an object or one of its properties, use the IsValid? node first to see if it's an existing object. If you try to act upon it and it does not yet exist or has been destroyed, you will get this error. Sometimes it happens when you don't even call the function that would fire it. Always check your references (and in C++, your pointers).

This is usually caused by having two events (Like say, On Key Press A and On Key Press B) in a blueprint that have flow of control cross over between them.
This causes memory corruption style issues, and often in completely unrelated areas of blueprints something fails with the mysterious "Access None" message.
Also I do not recommend ever having variable access and such cross between streams. That is just ugly and not supportable.
It would be nifty if the editor detected function crossover like this. It would have saved me a ton of time and headaches.
So here is an example.
And here it is fixed....
