If want the easy way to get 3 mil and be able to produce them keep the ship small. If it's big once it crashes it'll crash whenever you place a block. Scion of Earth was just a 960m long block so I can have toughness and still mass produce. If you want a 3 mil flagship on an IPad 2 warp. The game will crash when your dragging down the base. Actually I don't know, my attempts at a flagship all crashed when the ship passed 4.4*3.7km so yea...

Try to keep the dimensions small if you want to minimize crashes. Don't try to make the longest and widest ship possible. Also avoid super complex shapes. Like making super spindly hollow ships will make it larger and add to the chance of it crashing.
