In the console, this warning appears A LOT, usually, when a new part of the map generates.
I don't know exactly what this warning means, but if I remember correctly this can happen when the LuaVoxelManip tries to access an area of the map it was not supposed to access (ouf-of-bounds error). But I might be wrong.
Anyway, the fact this warning appears very often might be a sign that something deeper is wrong in the game.
