Just wanted to higlight this bug, since it is still in the game. However, after some testing, I found out that it can actually be fixed by changing the keybindings to a key that is not the normal one. So you have to change it from the defaul one to make it work.
Still no patch to fix it, today 15/11/2018.
I wont buy again any Origins games. Cheers.
I've tested this again and the conclusion is that it is still bugged.
If I reset the keybinding of the siege mode to "2", it will activate the ability but it won't do anything. If I change the keybinding only of that ability to "R" or even "5" it works.
