Compiling a large blueprint causes PIE delay until restart?

When I launch the UE4 editor for my game (build and run from visual studio solution), and then press Play in Editor, the game starts almost immediately. If I compile a small blueprint and press play, it also starts quickly. But after compiling my characters blueprint which requires a lot of nodes and functions, and then pressing Play in Editor, I must wait around 10 seconds while the editor is non-responsive until the game has loaded. This delay occurs on subsequent plays until one restarts the editor.

I thought that everything would be compiled and ready to go after one clicked on “Compile” for the blueprint, so there shouldn’t be any extra delay then. I don’t know if there might be some kind of memory leak or something. I still have several GB:s of ram to spare after compiling the blueprint, so it doesn’t really seem that low ram is the cause.

Are there any ways to solve this other than to repeatedly restart the editor? Since I do a lot of play>test>change>repeat cycles waiting 10 seconds each time really cuts down on the speed.
