Just tamed a 150 on a 5x taming unofficial server. DodoDex said 8 beers, which has been fine in the past. This time it took me 13 beers. Not sure what's been changed, but be sure to bring extra while taming! I didn't have to wait the 5+ minutes between the first and second feeding and the time between feedings was much quicker then usual. DodoDex has been notified of this issue.
