Severe case (all the items):
  1. Open the Players debug overlay
  2. Spawn a couple (dozen) items (NOT the Multiple Companion Cube)
  3. Watch the network "Suffering" indicator bounce around in single-digit range, sometimes reaching low multi-digit
  4. Spawn the Multiple Companion Cube item
  5. Watch the "Suffering" indicator skyrocket to >120
  6. Despawn the Multiple Companion Cube item
  7. Watch the "Suffering" indicator drop back down to 0 only very slowly
Worst offender (just the Multiple Companion Cube item):
  1. Open the Players debug overlay
  2. Spawn only the Multiple Companion Cube item
  3. Watch the "Suffering" indicator slowly climb to ~100
  4. Despawn the Multiple Companion Cube item
  5. Watch the "Suffering" indicator drop back down to 0 immediately
This causes an issue where remote players that have multiple items spawned, especially the Multiple Companion Cube, will appear with a very large delay ("Fnl D" indicator in the player list) of ~4-5 seconds.
