Reproduction Steps - I often had moments that during extended playtime the game started having massive frame-drops mostly on the main farm and ||savannah cave|| but this is a first time crash to the Xbox menu.
I just attained an A grade on my town rank and went around talking with people for their dialogue, handing some gifts around and at the end of the day I wanted to place down some Javanese outdoor lamps when the game just started to become totally unresponsive.
Now that I think about it I used TNT inside the caves so the frame drops can either be caused by the building/placement mode or some form of light issue. After placing around 12 to 14 lamps around the farm the game stopped functioning.
Repro Rate - For now this is a first time.
