I tried to open a biospheres map and I was on for about 1 second then I crashed.

What I expected to happen was to be able to open this map and play on it.

What actually happened was that I opened it and my minecraft crashed after about 1 second of playing the map.

1. Open minecraft
2. Open Minecraft Biospheres World map
3. Wait 1 second
