I only have one lion, which used up nearly all of my conservation credits. I don't have enough conservation credits to purchase a second lion and they never come up to buy with cash. The only animals I can buy for cash are the really common ones that sell for hardly any conservation credits. So I don't see how I will ever get enough to buy a second lion to breed so I can join in the community challenge before it is over. And if I don't join in, I won't get any conservation credits as a reward, putting me even further behind. I was really looking forward to the community challenges. Does anyone else have this problem? And can anyone suggest a solution? Thank you.
