PC Lighting Array Crash

[MontezumaI]

I was building a castle, and took a snapshot of it. About 15 seconds later, the game crashed.
The log says:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

I have included the snapshot in case that means anything
In the snapshot, it would appear some of the liquids and obsidian platforms aren't rendering. I guess I can post that in bugs.
