Why, after compiling, am I seeing an event node that is showing out-of-date?

I’m currently trying to compile a Blueprint and experiencing 2 fatal issues, both appearing in the log as “Event node (none) is out-of-date. Please refresh it.”. Does anyone have any ideas what’s causing this this and how to fix it? So far google has been rather unhelpful.
Thanks in advance

This popped up for me.

I removed the blueprint interface I hadn’t fully setup and the error went away.

It also happened to me when I tried to add a pin to send a copy of Self through the interface.
Removed the pin, and the error goes away.
