Troubleshooting Tips
  • Missing the 48h window? You’re just going slower — keep stacking tends.
  • Low-quality tends? Move to a hospital bed, clean the room, use better medicine, use your best doctor.
  • Serum cured the “wrong” problem? It targets the worst condition. Heal/handle other conditions first if you’re gambling.
  • Penoxycycline? Def says it blocks Malaria, SleepingSickness, Plague — not muscle parasites.
