There's also one marker south of the main farm next to the railroad. I don't think it's a problem they're there (editing them out is simple), but they should probably be somewhere else.
Not complaining, just informing, this is just the map I was looking for and I appreciate all the effort put into it.
Its possibly there for the train rental. I always play the game with markers and help icons off so I didnt notice them. I appreciate you telling me about them though. I will remove/move the ones I can in the next update. The field 5 one males zero sense to me as nothing I can find should be there according to the xml
