The Super Mario 3D World theme has a problem.
Last night while playing Super Mario Maker 2 I discovered a software bug that I was able to replicate myself with the Maker. The bug will get Mario, or whomever you play as, stuck in a Warp Pipe and not able to do anything at the software level. System level features such as the Home and Capture button will still work. If time runs out during this glitch the game will still be stuck as Mario seems to have vanished and is unable to die.
Replicating this glitch requires a few elements. First, it only works in the Super Mario 3D World theme. The other components necessary for this error are for Mario to be in a Cat Suit, and to use a Warp Box, Warp Pipe, and one Block in a very specific way. Once Mario is in a Cat Suit have him enter a Warp Block. Then make sure he comes out of the Warp Block directly on top of a working Warp Pipe with a Block directly next to the Warp Block but away from the Warp Pipe. As Mario enters the Warp Block hold the down button to instantly go down the Warp Pipe as he re-spawns and you’ll make Mario vanish confusing the game. The only way to get out of this situation is to hit the Home Button and to close the game.
This bug can also be replicated on the title screen if it happens to randomly pick a saved stage with the proper components to use there.
Hopefully this problem gets ironed out in a patch, but until then be aware since it’s possible to lose progress on a Stage you’ve been working on if you accidentally trigger the glitch and haven’t saved before then.
Super Mario Maker 2 is a complex game with a lot of things that need testing and other bugs have been discovered. However, this is the first bug I’ve seen that locks the game. Let us know if you find more.
