Thank you for your comment!
To clarify, this is not a bug! Some events have requirements to be unlocked!
Even if the player increases the level of the female characters, this is still not enough to unlock all the events!
To unlock level 1 (hug), you need to activate Dayani's level 1 event here:
To unlock the other variations of the "firewood collection" event, you'll need to complete the main missions until you unlock the gift events!
