Is my project getting corrupted?

I get this error everytime I load my project and it stops me from compiling this blueprint. It is only fixed by refreshing the node.

Any ideas?

Have you changed the definition of that function?
I have had such errors when I change the definition, At least the ones I have made in C++.


It is a blueprint only project. I have not added any plugins either.

What do you mean when you say “refreshing the node”?

Right click on node -> Refresh. It compiles ok then but I get the same error when I load the project again.

Have you tried deleting the node and then adding it back in?
But, Did you change the definition of the node when the error started?
