Animal Crossing: Wild World Bug
From 4 color rebellion comes a warning to Animal Crossing: Wild World players about a bugged gift item that has the potential to wreck homes and villages.
From what people have been reporting, you’re receiving a letter from _blank_, marked as “From ” containg a gift named “Red Tulips”. The letter contains no content whatsoever and has no closing. The item shows up as a piece of furniture (green leef) and this is where the fun begins…
The gist is that if you drop the item somewhere, you'll lose that space forever. The space where you dropped the item will empty, and you can walk over it, but you will be unable to place another item over it or push furniture over it. If you drop it outself, it will plant a sprout no matter where you are, even on concrete. In short, if you get the letter, just leave it alone. If it's really freaking you out, you can apparently sell it to Tom Nook with no ill effects. For the curious, there's a video of the item in action.
According to a 4cr contributor, a Nintendo representative said the letter is not a glitch, but an unfinished letter that was sent out accidentally. Nintendo is currently working on a fix for those who have already dropped the item in their game.
