Strange behaviour when Inferno generated at lower Y levels

[iojw]

Not a serious issue as it doesn't affect the module at all, but just noting it down here.

Earlier back in the initial testing, I had set the Y value of the dimension at around -2,000,000.

This caused strange behaviour when the player entered the dimension. I tested further and it seems that at extremely low Y levels, the player would just fall through the blocks as though they weren't there. At slightly higher Y levels around ~-1,000,000, I found that the player often got stuck in the blocks when walking along a level surface in the alt dimension. Occasionally, ghost would also stop working, whereby I could only move forward and backwards (spacebar and ctrl would do nothing to change the height)

The problem seemed to disappear at higher than negative 1 million, which is why I ultimately went with -100,000 depth.

You can test this out in game simply by changing the INFERNO_DEPTH under InfernoWorldGenerator.java
