I'm not sure if you know about this glitch already, but i figured out a way to duplicate buildings
i was making an agridome in the Plymouth campaign but decided last minute i didnt like the spot, so i moved the convec away. It was right when it started making the agridome, so it started building without a convec. The convec still had the agridome in it so i had it build next to the self constructing agridome, givign me two for the price of one.
perhaps i ninja'd the trigger starting the construction and the one freezing/making the convec invincible :ph34r:
