I thought introducing rounding into my Miner League slime code would help me simplify things when I worked in displacement... unfortunately, I told it to round up. Now, the first time a lake's surface is disturbed, it begins a chain reaction that ends with a bubbling sea of slime covering the entire land. It's quite an interesting effect, I've decided to let my test run... so far, the lake has consumed three mountains and half of my CPU. The moral of this story (and the reason it's not in babble) : a few extra decimals here and there can quickly add up!

[EDIT] On the plus side, I now know I can have a moving, bubbling, lake of slime straddling 17 sectors (170 squares, for the uninitiated) and only using 200% of the clock time. Chalk one up to efficient coding!
