When I open a project there is a single blueprint that throws a compile warning form time to time.
I can open the blueprint, hit compile and it’s all fine though. I’m not sure what is causing it or how to resolve it as the blueprint itself is fine.
I am moving this project around using dropbox though so maybe it’s a caching thing?
could you please post an image of your blueprint ?
The blueprint is pretty chunky, I can’t get a picture of it all and be legible.
I’ve taken shots of all the nodes showing an error and cut them together.
Hitting compile fixes the errors instantly.
Ok, So I tracked it down, had to pull it apart node by node.
I had a cast to a game mode (top right of the previous image) that was freaking out every time the project was opened.
I fixed it by removing it and replacing it with an interface. Works nicely now.
In my case I found out that there is a name conflict for my interface event. But there wasn’t any duplicate. I just fixed it by deleting the previous interface function and created a new one. And it worked perfectly. No more errors on startup.
Hope it helps.
