Me, @McDomo69 and @motssojosh are building a Dino Park. Due to a server restart, we lost the location. There was about 65-75 stacks of dirt making up the island. It is in a ocean. It is also a big dirt square. Reward: Domo said he would give a cow spawner to who ever found it, Ill throw in 4 nether stars.
I still have the cash to pretty much claim anything lol - I don't care about Money top ^^ I've been there since the last Map, someone else can take my spotlight ;p
Not sure about prism, but cp has a lookup function that can search for blocks a player placed, and it prints out their coordinates. I assume Prism has a similar functionality.
