thanks.
it is error in zero-K, some things in unitdefs_post.lua do not check for nil values:

[f=0000000] [defs.lua] Error: Failed to load unitDefs
[f=0000000] Error: 2, gamedata/defs.lua, [string "gamedata/defs.lua"]:38: [string "gamedata/defs.lua"]:26: error

2, gamedata/unitDefs.lua, error

2, gamedata/unitdefs_post.lua, [string "gamedata/unitdefs_post.lua"]:489: attempt to perform arithmetic on field 'buildtime' (a nil value)

a pity because this map is genius.

all units are blind because it is so dark!
you must play by feel.
