Typing something like ```dorf2.php?a=25&id=20000&c=d6F``` where ```id=``` is the position in the village will get you an error if the id is higher than 40 ( not including WW id=99). ```Unknown column 'f20000t' in 'field list'```
So I added this restriction when building. Although it fixes the problem, you can still build at WW position, bugging your building and not being able to use, or demolish it.
