Nah no time wasted...it's a bit frustrating, and not completely intuitive in KC, there are other multicast options that are considerably easier such as HKN and IS/ISBoxer. If you want to stick with KC since you have a subscription to it, then just give it a break and work with it on an alt team till you get the kinks figured out. Then migrate your main team over to it. That's what I did and it helped quite a bit.

Good luck to you I hope you figure it out one day
