April Fools Day was yesterday, I'd like my snapshot 2013b worlds back now please.

Put the summary of the bug you're having here

What I expected to happen was...:
The April Fools Day Infinity snapshot was supposed to go away after April Fools Day had ended

What actually happened was...:
I still cannot see my world that had been updated through snapshot 20w13b

Steps to Reproduce:
1.  I'm not technically savvy enough to separate my snapshot worlds

2. I'm stuck waiting for a new version 1.16? and not sure what will happen to my worlds if I attempt to open them in 15.2
