a discovery I feel I must share....
When I attacked Coruscant as the Rebellion, I noticed that my repulsorlift tanks would not move, and I thought it was some glitch. I explore some more, and I find an Imperial structure called the Repulsorlift Jammer, that disables any enemy repulsorlift vehicle. Plus, I noticed that it was not included in the manual or the strategy guide and I could not build it even playing as Imperial. Strange.....
But, if you already know this, ignore me.
