you left a message re overlapping - delete all overlapping from what i gather and start again I dont really know trying to sort it out myself!

i have a question about overlapping farms..i have never done it but sometimes when i'm plowing a couple will overlap without me doing anything? so does this mean i'm gonna lose everything or can they tell that it wasn't done on purpose? cuz i honestly didn't do it ...it just seemed to happen on its own and it's only a couple plots that got it?
