wonyoungie1138 There was something wrong with both neighborhoods back when EbN was first released, but not all the time and not necessarily with every lot. The pond and tree lots were the worst offenders, but that didn't cover everyone; and there were some issues with fairies and custom skin details, but that was said to be fixed a while ago. Still, you've found an obvious trigger for the crashes.
It's also possible that this is a newer in-game issue that you're only triggering in specific scenarios. Did you try your old save, or did you test Sprucederry Grove in a new save? Did you test the same lot and/or perform the same actions?
