The above video is from the MRP included below.
Steps to reproduce
- Load the included MRP project
- Start the game (main.tscn)
- Let the particles simulate for a little to see how they're supposed to be behaving.
- Press SPACE to pause the game. Wait 5-10 seconds
- Watch particles behave weirdly.
- Press SPACE to unpause the game to see even more chaos before the particle system returns to normal.
