Hello! I'm trying to convert devland map from 8.0 to 8.6 and i've got huge problem. After chaning proporties to 8.6 many places at map are unable to read by map editor. I mean the grass field is not grass field it's just piece of red block. It looks like this.
The ID of these red block is 4756. Anyone know how to replace this id to another or just convert map without any problems?
