When downloading themes from https://theme.muos.dev/, I found a few that returned dead links. Please see below as most of them (with one exception) can be fixed by modifying the link address.
GamePal Night - K. Torden returns the following dead link: https://github.com/MustardOS/theme/releases/download/2025-04-28_1039/GamePal.Night.-.K..Torden.muxthm ; link should be https://github.com/MustardOS/theme/releases/download/2025-04-28_1039/GamePal.Night.-.K.Torden.muxthm
GamePal.-.Sober (horizontal) returns the following dead link: https://github.com/MustardOS/theme/releases/download/2025-04-28_1039/GamePal.-.Sober.(horizontal).muxthm ; I think this is just a bad duplicate of GamePal - Sober Horizontal and should probably just be removed
