Describe what you thought should happen here

What actually happened was...:I created a fer, loaded them successfully, then the next would only partially load and not go beyond sometimes only 15% , at other times perhaps as much as 30 something %.
Describe what happened here

Steps to Reproduce:
1. Create and close down a world.

2.Go to recreate it, Go into More World Options but close it down before you create it. (I'm doing this to look up the seed number in order to search the nearby biomes.

3. Repeat this several times until loading the new world sticks part way
