Issue: Upon blocking a blow with a shield, zombies will not strike (or be able to strike from grace period?) if shield is held continually.
Steps to reproduce: Block a melee attack from a zombie and hold shield in raised position then lower.
This occurred in a cave when there is not much room to maneuver, back may have been up against wall when this occurred.
Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time.
