I’m afraid that no matter which civilization you choose, for some major reason, you can’t do something as simple as moving a trebuchet to another island. Unlike the Age of Empires 2 HD and the Age of Empires 2 The Conquerors, Age of Empires 2 DE wouldn’t allow you to move the trebuchet across the sea with the transport ship.
Please developers, fix this issue very, very soon.
Don’t take this the wrong way but I hope it’s not another of those double standards or whether the developers made that choice in which I might have to use other methods if I can’t get the trebuchet from one island to another island as a simple example.
Anyway, even if I’m wrong, still, I’ll give it my tick of approval if that absurd issue can be resolved in the future. Ignore this if you want but please don’t leave it unsolved for eternity. Thanks.
Well, until you wait for them to fix it, you could use bombard cannons, rams, or build the treb on the island you want it on. Not ideal, but it would probably work.
