Has the pathfinding gotten more bugged since last time I played?

[Myes!]

Suddenly, artillery ordered to target a specific brigade will start physically moving up to the target as if given a move-order, Videttes won't shoot at given targets, (They'll move up within range and skirmish back-and-forth, but never actually discharge their guns.), and the bug that causes deselects to be interpreted as "move infinitely in a random direction" seems to occur even more often than usual.
