As stated in the title, many assets in the game have unloaded
Went to the museum after a fossil hologram was completed (velociraptor i believe) and invited Lily to hang out at the Recreation Center to do volunteer gardening from around 7:30 am to 9:30 am. Everything was normal in the cutscene but when we said goodbye, a bunch of assets had unloaded and were not reloading even after entering heart events with other islanders. Island only repaired itself after entering and exiting a building
I only have experienced this once
