So I started a raid and finished it too. But about 5 minutes later, my world crashed. Probably the internet cutting out for a second, no big deal. But after I relaunched the game, I saw that the raid bar was back and full, but no enemies were spawning. It doesn't really affect gameplay, other then the fact that I might not be able to do more raids with the same village, but the full bar at the top is pretty annoying. Thank you for your time and patience.
