Hi, I normally play AoeHD and now decided to play with my friends on voobly. It seems AoeC2 lacks lots of useful stuff. For example, I selected 5 archery ranges and clicked on arbalest. It should normally produce 1 arbalest from each building but it just produces 1 arbalest from one and only one building. Also, attack move command doesnt exist etc... What should i do?

If you click one arbalest, it will produce one arbalest. That's intended behaviour. If you click 5 arbalest (or shift-click once, which is the same thing), it will produce one from each archery range as long as MQ is enabled (toggle next to the tech tree button in the game lobby).

Attach move doesn't exists, but you can use the patrol command which does the same thing except the units will move back and forth along the path.
