Online play affected, offline characters don’t seem to be affected.
I’m playing Rogue with Umbral Blades + Synchronized Strike and there’s something wrong with bladestorm targeting of further targets (very visible on blades thrown by shadows). Having some foe targeted is connected to it (my first thought was that this seems like desync / client prediction issue), it works as expected if I manage to target the ground.
Generally, it’s fine to target a moving foe in area size of target dummy ring around character and bladestorm lands where I click, but if I aim it further away (targeting is very unreliable near the border of screen) and it just flies in direction I’m aiming, but travels further at random (even completely off of screen).
