On PVP servers at raid time specifically after explosions go off sometimes the fire effect will stick around causing the server to become incredibly unstable
Side note: If this issue can be fixed I’d also suggest making the fire effect from bombs to merge into one damage over time effect rather than 1 per bomb to reduce lag even further since if someone sets off 50 bombs at once that makes 50 DoT zones in a space that could be covered with just 1.
