The bug

When falling on a block, the particles produced render behind the outline of the block that the player is targeting. I could not reproduce this with any other particles.

This can be reproduced using Fast and Fancy graphics modes. It has been fixed since the creation of this report in Fabulous! graphics mode.

How to reproduce

1. Place a block down (any block that produces particles when a player falls on it)
2. Build a tower next to this block that is at least 4 blocks tall (the taller, the easier it is to reproduce, as more particles are produced)
3. Fall from this tower while targeting the block you will fall on
4. If a particle produced lands on the ground in the same place where the block outline renders, you will notice that the block outline is shown in front of the particle.

In the screenshot attached, I have circled the particles that show this issue in pink.

Please note that particles that do not land on the ground are unaffected by this and render in front of the outline. Make sure that you wait for the particle to reach the ground to test this bug.
