What I expected to happen was...:
Tap to open or close a wooden door, expect to hear the sound effect.
What actually happened was...:
Intermittently, for a door or two, no sound would be heard. Normal sound would happen most of the time, no sound for a few doors at a time.
Steps to Reproduce:
1. Tap to open or close a door placed in the game.
2. If there is a sound, move around for a few seconds and open and close the doors again.
First noticed playing a freshly created world using the Skyblock seed. Doors are typically surrounded on all sides by stone or cobblestone.
