Corner lots "front" defaults

I'm having the same problem time to time as well. I don't think there's a way to change which side of the lot is front. It's just the way it is by default map design of the game. You can choose the front door whereever you want but it won't change where sims will spawn when you load the lot. They will always spawn in the default "front" side.

@LindsaySeddon1 By the way, there's this empty 40x30 lot in Windenburg called "the summer home". That lot's front is actually the long side of the lot. You can place your house there.
