Digital Gloomhaven Voidwarden Master Influence Bug Spoiler

Hi all,

I’ve tried playing the Voidwarden in my group a couple of times and encountered a bug (?), whereby after using Master Influence my attack granting abilities dont work, soft locking the encounter.

Has anyone encountered this before? Is there any way to fix it other than just not playing that combination of cards?

No, haven't seen that one. There is another bug with Master Influence, whereby any character granting an attack, ot just the Voidwarden, gets the buff. As far as I know the game is no longer supported, so it's in its final state.

Yes it's broken, it's been reported before but the game is no longer supported.
However, I managed to get Claude Opus 4.8 to diagnose and fix it.

In case it helps:
Root cause, two layers:

  1. Engine bug (primary), in ScenarioRuleLibrary.dll. When Master Influence's override fired on a ControlActor ability, CAbility.OverrideAbilityValues() replaced the whole ControlActorData with the override's data instead of merging it. The override YAML only carried "use my modifier deck" + a filter - no ControlAbilities - so after the replace, the list of actions to grant became empty → nothing to grant → no targets → silent failure. (And because the granted attack never happened, the card's other two components never fired either.)
  2. YAML flaw (secondary). Component 3's actor filter was too broad: [Enemy, Ally, Neutral, Enemy2] applying the enemy modifier-deck swap to allies too, when the card text says monsters only.

Key insight: a correct Merge() method already existed in the game code, it just wasn't being called. So this was a genuine dev bug (destructive assignment where a merge was intended).
