I don't know if this a bug or not bhut for some reason whenever you play music on a music brick it skips 1 second after the song is played and then it plays normal.
Also In Fullscreen, when turn audio off by changing OpenAL to None and Put it back on by reselecting OpenAL, followed by alt-tabing to get to desktop and back to Blockland.
All of the brick sounds are all forgeted up, sometimes planting a brick is glass break and spawning is plant brick, and sounds play at random times for no reason after that.
The only way I could fix this is by Re-starting Blockland, I have re-created this glitch multiple times.
