Hello,
- This error is happening in a project I am working on, no code changes, just content (i.e. Blueprint project).
- Class Defaults links that break are an issue, but I believe they are a separate thing. I could work around this until the bug gets fixed.
They way it looks, there is some sort of nasty cyclic dependency that does not get resolved on editor load. I am attaching a few screens, but I am not sure how helpful would these be.
And if I save that BP in that state and close the editor, the editor would not even load again - crash with no decent callstack at 93% load - need to revert that asset.
