Returnal's a pretty solidly-designed game overall, with only the most minor of bugs occasionally cropping up and making a current run through its biomes that much more challenging. Biome, what a fun word to say. Like any game in the modern age, developer Housemarque had a patch locked and loaded to fix up any lingering issues, but the latest update may have had the unfortunate side-effect of uh…wiping save-games.
