Upgrade stats/cost?

Can anyone post a list of the cost and durability of upgrades after the last update?

Tier 0 (Twig)

Old health
50

New health
10
Tier 1 (Wood)

Old health
1000

New health
100
Tier 2 (Stone)

Old health
5000

New health
500
Tier 3 (Sheet Metal)

Old health
8000

New health
200*
Tier 4 (Armor)

Old health
N/A

New health
1000

But what resources do I need for the reinforced tier?

Tier 0 (Twig) = 10 wood (doors take 100 they are wood tier).
Tier 1 (Wood) = 100 wood
Tier 2 (Stone) = 100 stones (no door)
Tier 3 (Metal Sheet) = 100 Metal Fragments

Tier 4 (Armored) = its supose to need 100 of wood, stones and metal frags, but for now its bugged.
Armored are taking 100 stones and 200 metal frags (if you have 200 metal frags).
If you grab only 100 metal frags you can upgrade to armored. (on screen will say the cost was 200 metal frags).
So for armored, if you do the 100 metal frags each time, it will be consume only 100 metal frags and 100 stones.

That is what i know, someone correct me if i’m wrong.
