Crash Replacing Village Doors

After quickly replacing a wooden door with a dark oak door in a village very rapidly (different doors, not all the same doors), and villagers cluster near them, the game instantly crashes and I am not sure why.

The crash report wouldn't drop down so I gotta C+P. Sorry about that.

If it helps the village was a desert one.
