New village type and new house type in the plains where there is a  lot of Acacia wood (savannah)..

This new house type has a Yellow Terracotta extension on the roof and is surrounded (at the corners) by Acacia wood columns..

The Corners of the house don't have a block present, so villagers, when waking can spawn through this corner block, diagonally.. The villagers then get trapped outside the house (in the corner) between the walls and the vertical wooden columns. I've spotted two villagers trapped in the same space..

Fix, I guess, would be to either remove the external wooden columns (at the corners) or place acacia wood blocks at the corners (like the other walls)..
