Logged into the US server and found a new room

I wrote a post earlier about Soul Crystals. I was about to sell my Soul Crystals, but I was curious about the US server (and I happened to have a paid VPN subscription), so I logged in and found a new room. On the US server, a Dragon Breeding room has appeared where the attendance reward room used to be on the Korean server. The attendance reward room appears between the location where Kali's reward pops up and the original attendance room. Initially, there's a guide, and they give you a free dragon if you breed one. It seems like there's a time requirement for breeding, similar to the Dragon Missions. I really hope they bring this feature back to the Korean server too ㅠㅠ Anyway, after this room unlocked, when I merge Dragon Trees, there's a low chance of getting a bonus Soul Crystal. I guess they want us to collect them for breeding. Flawless Soul Crystals probably give good dragons, and regular Soul Crystals likely give normal ones.
