Maybe about 30 minutes or so.I had pwps in most spot so it made it very limited, and all the other villagers basically got good spots on the first or 2nd try so it got down tohave very limited placed to place houses ;-;
If it takes me more than a few hours I just give up and let them plot where they aren't ruining my paths. I hate it when they're like 1 or 2 spaces away from where I want them to be -.-
i dont plot reset but i did do it once for marina oops it was like 30 minutes and im glad i did because if i didnt it would have been on all my hybrids cry
