Obviously this album is twice in the catalogue... That's why I was able to buy it mistakingly twice, which normally is not possible within Bandcamp, because, when you own an album, it's in your collection und you are not able to find the "Purchase Info"... I didn't want to buy it twice... So I ask myself, is this a system failure or did you trick the system in putting it twice in the catalogue with sligtly different credits?
