I'm not aware of a general bug with the potions. Maybe something is wrong with the game files and a re-download of the full version could solve the issue? What system are you on? Can you post a screenshot of the error or the full error text?
well I'm on Android and if I redownload I think I might have to try again I can't post the error text tho yeah the text its gone but the entire world got corrupted like some quest are reseted and for some reason I lost like half of my currency and then dorgania border is not open there is a bunch of things but I'm currently trying to recover again
