-	// When we play a replay back in headless mode, we want to skip the update of GameClient
-	// because it's not necessary for CRC checking.
-	// But we do update the particles. The problem is that particles can be generated during
-	// GameLogic and are only cleaned up during rendering. If we don't clean this up here,
-	// the particles accumulate and slow things down a lot and can even cause a crash on
-	// longer replays.
-	// TheSuperHackers @fix bobtista 02/02/2026 Use update() instead of reset() to avoid
-	// use-after-free crash. reset() deletes all particle systems immediately, but DrawModules
-	// (W3DTruckDraw, W3DTankDraw, etc.) hold raw pointers to particle systems. When those
-	// DrawModules are later destroyed during game shutdown, they crash accessing freed memory.
-	// update() only cleans up finished particle systems, leaving active ones intact.

+	// Update particles to prevent accumulation in headless mode. update() has slightly more
+	// CPU overhead than reset() but is semantically correct - particles finish naturally.
