Every update a game gets is supposed to make it a better experience, but there's always a risk that things could go a bit wonky in other areas. Unfortunately, that's what's happened with Animal Crossing: New Horizons's Version 1.3.0 update.
Some players are are reporting that the game's latest update has caused an issue with bridges. When they go to cross a bridge, they are met with an invisible wall. Obviously there are still other ways to get around, but not being able to use your bridges is quite annoying! Nintendo will surely have an update to fix this bug soon. Until then, get ready to take the long way around your island.
