PostCampfireSubscriber is called before and even if the action is canceled.

[GniLudio]

Called before action

PostCampfireSubscriber is called before the action(that is selected) is used.
Easy to test with low health:

System.out.println(AbstractDungeon.player.currentHealth); // prints the health before healed

Called even if action is canceled

If the Smith is selected, the player can still choose something else.
This is misleading, because the method even gives the option to allow another action.
