Just used a Lunging Thrust to move and had Unstable Bolt in hand. There was no roll for Unstable Bolt even though Lunging Thrust is also a move card. I haven't yet tested if this happens for all step cards or if it was caused by not having any targets for the attack part of the card. -- BATTLE LOG: Scenario=Workshop Level 2,Room=WIZW (Zalminen),RoomID=2279,Msg=The active player is now Zalminen BATTLE LOG: Scenario=Workshop Level 2,Room=WIZW (Zalminen),RoomID=2279,Player=Zalminen,Actor=Shalar the Blue,Event=Move,Origin=(4, 7),StartFacing=(-1, 0),Destination=(3, 7),EndFacing=(-1, 0) BATTLE LOG: Scenario=Workshop Level 2,Room=WIZW (Zalminen),RoomID=2279,Msg=Player Zalminen must select targets BATTLE WARNING: Scenario=Workshop Level 2,Room=WIZW (Zalminen),RoomID=2279,Msg=Invalid action: Lunging Thrust, played by Shalar the Blue - too few target actors (0/1) BATTLE LOG: Scenario=Workshop Level 2,Room=WIZW (Zalminen),RoomID=2279,Msg=Action: Lunging Thrust is invalid - cancelling BATTLE LOG: Scenario=Workshop Level 2,Room=WIZW (Zalminen),RoomID=2279,Msg=Lunging Thrust was cancelled. BATTLE LOG: Scenario=Workshop Level 2,Room=WIZW (Zalminen),RoomID=2279,Msg=The active player is now Gary -- EDIT: got a new chance to test it, this time with an attack target near enough. Unstable Bolt rolled normally. So it looks like the bug only happens when you use a step attack and only move with it.
Still weird though; Typically Unstable Bolt rolls before the move even takes place, doesn't it? Why would it wait until it sees if there is a target to attack or not?
