Comment 3 for bug 1767976

Highest used preciousness is 14 now. And I think we should not go over 20 or 25. The minimum we can do is mention this range in documentation.

Additionally we can implement two limits:
- hard (100 as hessenfarmer proposed) when the game would fail to load
- soft (value to be mentioned in documentation) which would only print warning into terminal output.

But I agree this is not urgent issue...
