Launching level with "Launch" plays an outdated, packaged export

Title pretty much says it all. I have a level, and playing said level using “Play” runs it seamlessly. Packaging it with:

File > Package Project > Windows > Windows (64 bit)

will take a while, but it will eventually get everything packaged, and I can run it without issue. If I try to play the level with “Launch”, it doesn’t give me any error codes, and simply plays the last package that I exported.

I didn’t think that this was intentional, so if it’s not, does anyone know how to fix it?

Got it figured out. I just had to delete my

.../Unreal Projects/[Project]/Saved

folder, and it started working again.
