#77 atanks-6.6 crashes on land creation

[Sven Eden]

When trying to actually start a game, atanks crashes with a segmentation fault, because an illegal index in env.slope is accessed.

The following diff fixes the issue.
There were no "distortions" or anything like that in the landscape afterwards, so there doesn't seem to be a bigger underlying issue.
