The build server is working again! Updated the link in the opening post.
I have added support and settings for ocean monuments. The WorldConfig has the following new settings:
# Whether ocean monuments are enabled.
# Ocean monuments are placed on the corners of a grid, with a random offset added to each corner.
# The first variable is the size of the grid in chunks.
# Setting this to 5 will give a grid with cells of 5x5 chunks.
# Random offset from each corner in chunks, on both the x and z axis.
# May not be smaller than 0, and may not be larger than OceanMonumentGridSize.
OceanMonumentsEnabled is also available in the BiomeConfigs. Old worlds (and new worlds) will have ocean monuments enabled automatically.
