When playing as Regulus, turning on the "single click aggressive move" option causes him to frequently be unable to move while in combat. He can still fire just fine, and can use abilities, but will not move from his position. Not sure yet what allows him to break the stasis, which normally last for 5-10s, sometimes longer. Regulus does not need to be surrounded by units or in any way boxed in; this has happened with him standing by himself in the middle of an open field, with other units only at the limit of his range. He does seem to need to be attack for this to happen though. Not sure yet if it occurs with the other two characters. Couldn't find it anywhere on the bug list, unless it falls under the category of "known pathing issues."
