did anyone get the sinful vampire dragon? I collected 4 vampire dragons (bio-augmentation, envious, gluttonous and wrathful) I still haven't gotten the 5th "free" vampire dragon...

I am not sure what you are referring to but the Bio-Augmented Vamp is the first in the second vampire collection, the others have not been released yet. As to the first vampire collection you heed to collect Prideful, Envious, Gluttonious and Sinful in order to get Wrathful.

@nynaevelan thanks for the reply... I just started playing, the event just ended and stated "collect 4 vampire dragons and get the 5th free"
maybe it was just bad code leftover from a previous event... idk
