For example, when in PvP, the Jedi Consular is selected. I select another party member of the opponent, which works. I try to select the Jedi Consular again, but it doesn't work.
Another example from normal battle: A target with still high HP is automatically selected. The previously attacked target can no longer be selected, which makes it hard to focus fire power on a single target.
In all these cases, "taunt" is not active.
I have lost many battles because of this bug, and it is kind of annoying.
