Nintendo has issues a statement via their Twitter account and official website (thanks Vooks!) that players of the new Happy Home Paradise DLC for Animal Crossing: New Horizons may experience a gameplay bug that can cause issues with the expansion’s new content.
The exact details of the issues are unclear, but a patch is on the way to rectify the issue. In the meantime, Nintendo has advised players not to remodel their island’s residents’ homes while they have their airport gates open. Players should keep their gates closed before attempting any remodelling to avoid the issue.
We recommend players to not attempt to remodel an island resident’s home while the gates at their airport are open. As long as the airport gates are closed, you should not encounter these gameplay bugs when remodelling residents’ homes on your island. [2/3]
