Villager bug in action creation

[Vychron]

When an action block with a dropdown list of villagers is created, but the dropdown list is empty, the game sometimes no longer recognizes the a villager and makes the player unable to create actions for this villager.
As a result, 2 things happen:

1. The affected villager will no longer be able to have it's needs filled, causing it to gradually lower the appreciation of the village.
2. A new villager will take over the villager's spot in the game.
