Files get removed when extracting U8 archive

[bavario-lginc]

When extracting a U8 arc file from New Super Mario Bros. Wii, it fails and deletes the entire folder as you can see here:

This is reproducable on any arc of the game. However I do not have any other game that uses U8 (at least to my knowledge).
