Nintendo is working on a patch.
If you’ve purchased the Happy Home Paradise DLC for Animal Crossing New Horizons you may encounter a bug while playing the game. This bug occurs when players visit their Resident Services and ask to remodel a resident’s house while having their Airport gates open.
Your best option in that case is to close the game and re-launch it. Nintendo is working on a ketch to fix this bug and will be releasing it later this month.
