Villagers crowd into a single building

Villagers are not using houses made for them. They are staing in 2 or 3 houses ( of aprx. 150)
You can see on a pic, how they behave

What I suggest to do:

• make an array of doors in village
• make an array of villagers
• order every villager in villagers array to choose one door from doors array

For example, there are 10 villagers (1,2,3 ...9, 10) and 10 doors in the village (A, B, C);
Then each villager have to use 1 door, for example:
1 villager - A door
2 villager - B door
...
10 villager - J door

So, if the house contains 5 doors, there will be 5 villagers

I think, it's realy easy to realize, and I didn't get, why you haven't made this yet.

Thanks for attention.
