Graph of earth fragments as it runs

My two friends and I noticed that the bug starts after you start running, and the first animation is a small explosion/fragmentation of earth. However, it only happens when taking the first few steps while using the run command, and it doesn't continue during running or walking. This same bug occurs with lighter dinosaurs, and even inside caves. The animations alternate between earth fragmentation and grass fragmentation, sometimes in environments without vegetation, such as on top of a rocky area, where grass fragmentation occurs. It happens when running during the first few steps.
It also happens when you start running in a shallow area where there is water; it shouldn't happen because even if it's a shallow area, you're still in the water.

The fragmentation of stones and earth, or grass, only comes off in the first act of running and does not continue. And also in shallow areas of water.

Either the fragmentation should be continuous or it shouldn't appear at all, and it shouldn't appear in water. In rocky areas, grass fragmentation shouldn't appear.
