A few of the patrons at this event have sent in inquiries regarding the way players, masks, and abilities are resolved. In hindsight, I did not make it specific within the opening post, so here we go!
For this game, I find a good way to understand everything is to view it in a physical context. Each player in this game is effectively a patron at a ball. Their abilities are unique to themselves, and not to the masks. The masks are merely the face presented to the other players in the game. If a player swaps masks, they are still that same person, just with a different disguise.
So, following that logic, let us say that you have an ability that lets you target a player during the night. To target a player, you select one of the masks in the game, and in this case let's say you target Mask A, which is worn by Player X. However, should any mask scrambling occur during the night before your action takes place, and let's say now Player X wears Mask B and Player Y wears Mask A, then your ability will resolve on the target you selected: Mask A, which is worn by Player Y. As a result, Player Y is affected by your ability.
Additionally, let us say that this ability has a lingering effect that continues to affect Player Y. If during the game Player Y would then switch to another Mask, like Mask C, and Player Z ends up with Mask A now, then Player Z would not suffer from the lingering effects; Player Y would still have the effect, even though they changed masks.
The exception to all of this is if there is an ability or role that specifically states that a mask is acted upon. Basically, view the players and masks as separate entities, but you target the masks to act on the player wearing that mask. In a game of changing masks, it can and will get confusing, thus adding to the mystery of the masquerade.
If you have any questions about this, I will reply here. Additionally, if you have any questions about your role, I am always available to help. <3
