Anybody experienced same bus as Quartus II 4.1 synthesizes away declared ROM blocks with init-file?

I have 3 identical ROM blocks with each having its own MIF init file:

Code:
	rom1 red(
		.address({back[9:0],tile_delta}),
		.clock(~horizontal[2]),
		.q(tiles_c)
	);

	rom2 green(
		.address({back[9:0],tile_delta}),
		.clock(~horizontal[2]),
		.q(tiles_b)
	);

	rom3 blue(
		.address({back[9:0],tile_delta}),
		.clock(~horizontal[2]),
		.q(tiles_a)
	);

But only 1 ROM block is synthesized no matter what I do....though all 3 are using same inputs and outputs are driving VGA port...
