It hasn't been removed. You just didn't find it
nevermind, it was VERY FUCKING RANDOMLY MOVED TO THE RANDOM SECTION?? WHAT??
This is WORSE!! Objectively!! I didn't even figure this out until I found a comment explaining how to find it (press left/right on the random opiton in freeplay)
The fact this is never explained, partly thanks to the changelog not being updated, makes it really stupid.
