Hi @Districh-ru , could you please take a look at the wrong road placement? I am not sure what is going on.

@Districh-ru , also I noticed that we still put terrain via Maps::Tiles and then save the info inside MapFormat. This leads to a fact that road placement does not properly update terrain but let's fix roads first.
