Buffet worlds not Loading at all.

Okay. So I decided to challenge myself and pick a random biome to survive in (Mountains was my choice) and turned on cheats and Bonus Chest. I click create world and sit and wait for maybe a minute or two watching it load then watched a youtube video that was maybe 6 minutes long. I look back and the progress of generating the spawn area was stuck at 23%

I don't know if it's just my computer or if others are having this issues as well. I checked around and nobody seemed to. I also had this issue in one of the first snapshots.
