Detailed postmortem in sessions/2026-05-24-ghost-blocks-bug.md.

Quick fix

sed -i s/incoming-packet-threshold: 100000/incoming-packet-threshold: 300/ /opt/mc-stack/<server>/config/paper-global.yml
# Then restart MC via RCON save-all flush + stop

Cross-server cleanup

  • mc-ekaii — applied 2026-05-24
  • mc-creaclone
  • mc-plot
  • maison MC (if still active)

Why it bugs

Name is misleading. incoming-packet-threshold is a TIME WINDOW in milliseconds, not a packet count. Hardcoded limit is 8 packets per window. At 100000ms (100s) window, 10th placement = silent drop.

Full source code analysis + 5h debug log in the doc.
