Eyes of ender usually fall down, so you can usually use them multiple times, if you didn't. I think there are some ender eyes in the chest on the floor above the ground floor, behind the stairs, if they haven't all been used. But maybe we should wait with them until we organize one big run for strongholds or something, after 1.3 crop and stuff.
Idk how much mossy Spawntown has, but it's all in the building material chest on the ground floor. Probably not a lot. I don't think we have any cracked bricks at all.
