Hello.
Maybe you know how to fix, that some of the maps don't make grass? Normally, if path is unfrequented, it overgrow with grass and if Geolog find some resources, they dissapear after some time.
But sometimes, some maps are "corrupt" because the rules won't work. And it hard to function if all of the grass turn into paths, made stone... :/
How to fix that?

No one knows?

Which of the Settlers game are you talking about?

Settlers IV.
When I play some created maps, there aren't feature for "dissapearing" paths and raw materials. When Geolog find raw material - it doesn't dissapear after a while. Then when someone frequent use path, they turn stone, and don't grass back. After some time, whole map looks like one big stone. It's difficult to plant trees there etc... I know it's must be bug or something...But don't every maps has this bug... So maybe it can be fixed?

Sorry. I don't know a fix.
