Node () is out-of-date. Please refresh it. during packaging

I just migrated my project from version 4.15 to 4.18. I fixed all the errors that I found, but these few errors wont go away. When i look in their respective blueprints, they compile and the error go away. but when I go to package my game the errors return. Below is the error in question. This is causing my game to not package. I have tried to delete the nodes and recreate them but that dosent work. Anyone have any thoughts?

And if you play your project in the editor everything works as expected? No errors?

Yes it does. I think this is the error though, I will check it and see. I am using the menu toolkit from the marketplace.

Ok, would have been good to know. Also the standard UMG slider has a ValueChange event, so it was impossible to understand it from the error log. Well see if you can solve your problem following that thread, otherwise I am happy to try to help you further.

When you upgraded to 4.18 did you start with a clean project or reuse the existing intermediate directories?

Hmm, i created a new project and copied over the entirity of the content folder since that was mostly what i needed. Maybe I can try to remove them though the intermediates.

Definitely try a clean project. Easiest way is to package a zip from the editor and use that to make a new project.

Intermediate files can even get corrupted between builds of the same project.

But from your last comment, I’m not sure if that’s the issue. You copied the content over? You’re supposed to change the version of the original project (right-click the uproject file for the option). UE4 needs to upgrade the assets if it needs to.

Be sure to back up your original first tho!
