Game Tick speed won't set to normal

Just loaded the newest snapshot and after backup and first play, the game tick speed is way to fast. The sun moves to fast across the sky and when I harvest trees, the leaves just rain down... Not to include that the mobs just race after me.

I opened the saved game in LAN and turned on Cheats to try and set the randomTickSpeed to 20 which is the normal rate, but it has no effect.

As it is, I have time to go plant one or two trees and then night is setting on me.

I tested it in a new world and did not get the same results.  It's something to do when I changed the randomTickSpeed value earlier in the game to speed the growth of vines and set back, and it has broke the world.
