Recently I’ve been dealing with a strange issue where the built in nodes such as Event Begin Play and Event Begin Overlap are being replaced with Receive(EventName) nodes upon opening my project. This causes the blueprint to throw up warnings, but the only way to fix it seems to be just deleting the bad nodes and replacing them with the correct ones. This is more annoying than anything because it’s happening numerous times to random child blueprints and won’t stop. What’s causing this?
Hmm. I had a similar problem.
Although in my case it was custom events. Not built-in nodes.
Check for cyclic dependency with those blueprints. Worked for me.
