I think there might be a glitch where visits to Melody's doesn't count if you're on a mobile device. It's the only possible reason I can think as to why my count says 19 when it should say 20. I used my phone to come on and collect my gift a day or two because I wasn't by a computer. Is there any way this can be fixed and I can get my two days back? I guess I'm probably just screwed through technology though, ugh. I wanted my dang potion.
I think I saw Keith say they had a problem for some reason and to file a ticket if your count is wrong.
edit: ">here was that thread. but he said it only held people back one day. so it could be a reoccurring bug.
hopefully they can get it fixed for you. I linked the thread I saw that on in my previous post in an edit in case you were curious :)
