Animal Crossing New Horizons update 1.1.4 has been released by Nintendo, which tweaks the appearance rates of some Bunny Day eggs.

Following last week’s 1.1.3 patch, which fixed the Bunny Day Balloon glitch, Nintendo has now deployed another minor update for New Horizons. This new update aims to address an issue that caused Rex Kurushima to receive the Platinum Kogane bug and pass different items to different models.
