Checklist:
1) Max Happiness before leveling up
2) Night time
Things I have tried:
1) Relogging in then leveling Chingling up
2) Reducing happiness by causing Chingling to faint, then increasing happiness to 255, then leveling up
3) A combination of the 2 things above
Other things that I'm not sure if they have an effect on this:
1) I just evolved another Chingling right before this one (about 12 hours ago
2) I'm using a Soothe Bell
3) I'm leveling up at Mt. Silver Exterior
