Removes flame particles (#5055)

# About the pull request

This is a paid PR.

Allegedly fire was lagging the player. I assume the particles are the
issue.

# Explain why it's good for the game

Given the vast range of people who play CM with varying levels of
computer hardware it would be prudent to remove anything that may be
lagging players. Game feel good.
