Gnomes sometimes completely ignore encumber in this stage. Lost the code log, but here's the battle log. Arkand freezes Muxy! (Encumber 3, Duration 2) Arkand moved. Muxy took 4 Cold damage. Ponti runs Ponti moved. Squinti moved. Poki moved. Meriar dashes Meriar reacts! Â…but you are slowed by your Heavy Armor. Meriar moved. Ponti tosses a javelin at Arkand Arkand took 3 Piercing damage. Arkand runs Arkand moved. Jollo runs (3 move) Jollo moved. Muxy moved. Our friend Muxy moved all 3 tiles, as if he wasn't encumber 3.
Sounds to me like a collision between "minion code" and "yeah, Move cards are distinct from the concept of movement, thus causing confusion." So we already have the weird situation where the person playing the card is the only one the system checks for Encumber and Halt; and now we have a mob of minions all running from the same Run card. Who "played the card" in a group of minions? Everyone . . . and no one . . .
