I'm now going to be very careful about reading everything and reviewing dragons BEFORE committing to a Dragon Tales event.
1. bred Red Leaf late.
2. bred a Diamond and used several breeding boosts and gold to get it off the nest.
3. boosted and used gold to speed hatching Pale Vine. Game crashed and the boost was active but didn't affect hatching time, paid gold for entire hatch time.
4. boosted and used gold to speed evolving Pale Vine to level 10.
.... and NOW I finally notice that the Ultra Rare dragon is Sky Giant (fairy, white, green) not Sky Fairy. I have Sky Giant and still need 3 more crafting items anyway, so G'AH! WHAT was I thinking??!
I'm not going to waste gold on events any longer unless it gets me a Champion or Diamond type of dragon.
