Copper is not upgraded correctly from pre-21w05a worlds
Copper blocks aren't upgraded correctly when loading a pre-21w05a world in 21w05a. Some blocks disappear, and the fully weathered copper blocks revert into the penultimate weathered block stage. This is because the blocks were renamed and the block IDs were changed, but the upgrade paths weren't adjusted to accomodate that. This also affects their item forms.
To reproduce
- Load this world in 21w03a: 2021-02-03_19-53-19_Ghost Copper.zip

- Upgrade it to 21w05a

Some blocks are missing and the fully weathered blocks have jumped back a stage

Maybe because they changed the block names?
"The stages of copper oxidization are now called “Copper Block”, “Exposed Copper Block”, “Weathered Copper Block” and “Oxidized Copper Block” in sequence of least to most oxidized"
Edit: Yup
I can confirm beacouse it hapend to me 1h ago
I can also confirm, every block that had its name changed (the copper blocks) did not update properly.
