Unresolved compile Error (while there is no Error)
I have one blueprint which I can't compile to get it "clean", it's always "dirty" after compiling, but it does not give any errors on compile. It's just dirty. So that's not too awful since I can just ignore it and everything works.
The annoying thing is that every time I want to play my game this screen appears:
So I hit "play", have to wait ~15 seconds while the engine does whatever (I have compiling on hitting play disabled, so I really have no idea why I have to wait so long after hitting play) and then I have to click on "yes" to be able to start my game.
So I either want to be able to disable error checks for this particular blueprint or, even better, like to have the "always dirty" stuff fixed.
Is this a known problem? I have this issue since version 4.6. At the moment I use the most recent 4.7 branch from today.
I was able to reproduce this behavior with the MiningBuilding Blueprint in 4.7.3, and I've entered a bug report for the issue (UE-12129). I included a copy of the project so the developers have something to work with. I'll let you know as soon as I see any update on it. For now, it doesn't appear to be causing any issues during PIE, so you should be able to work around it (aside from the mild annoyance of having to click the Yes button before PIE every time).
I also checked this in 4.8, and compiling the same Blueprint crashed the editor. I've included that information in the bug report, but I wanted to make sure you're aware of it. Hopefully fixing one issue will also fix the other.
I'm not sure what's causing a long compile time for you, though. It's definitely doing something, but I'm only getting a few seconds delay at most. You might try removing the Intermediate and Saved folders from your project (make a copy somewhere, first!).
