A video of the bug is now attached.
@nothing999 Perhaps you can explain what you mean? The player waits for the indicated cool down to finish. (The player needs to hold the Use key on the second horn at the end of the first's cooldown to not make sound.)
The second horn sometimes plays and sometimes doesn't. I believe that makes this a valid bug, and the ticket should be re-opened.
Still here as of 1.14.2 Pre-Release 2. Or it returned
I suppose it's a matter of perception. In the right-handed example, the sound happens as the brush moves right, so I see the active stroke as moving right. So, the particles should move right too. I'm struggling to see the active stroke as moving left. If the active stroke is meant to be left, the timing should be different for the sound.
I got two people's input. One saw it as left, the other saw it as right. Fascinating...
