When I select the Dungeoneer's Pack it lists the encumbrance as 51 lbs.  But when I calculated the actual weight of the items, I come up with 61.5 lbs.  Am I missing something?

Can you check again? I calculated 63 lbs.

Anyway, containers will be revamped soon.

This is how I calculated it to 61.5 lbs:

• Backpack (5lbs)
• Crowbar (5lbs)
• Hammer  (3lbs)
• 10 pitons (1/4 lb each, total 2.5 lbs)
• 10 torches (1lb each, total 10 lbs)
• Tinderbox  (1 lb)
• 10 days of rations (2lbs each, 20 lbs)
• Waterskin (5 lbs)
• 50 ft. Hempen Rope (10 lbs)

Let me know if I have something wrong.

You are right. this is now fixed! Thanks!
