Wait, the user mentioned "nspupdate 10010rar verified". The NSP file is usually for official Nintendo Switch updates. If Moonlighter isn't a Switch game, an NSP update wouldn't apply. But Moonlighter was ported to Switch in 2020. So, if this is a 2018 update for PC, maybe the user is mixing up different platforms. This could be a typo. Alternatively, maybe there's an unofficial mod for the Switch version using NSP files.
