[MC-204526] Copper block dont turn into weathered state.

Copper dont change into weathered state, even the gamerule: randomTickSpeed is 10000 (hyper-fast), and weather is rain. (after 1 min)

Seems not to affect budding-amethyst.

Environment

Windows 10 20H1 [10.0.19041]
Java 1.8.0_51 64bit

AFAIK random tickspeed doesnt affect copper weathering, nor does rain. It takes about 60-80 ingame days to change state once

Copper doesn't use random ticks. It uses a separate mechanic, hence the predictable timeframe.

Maybe it's placeholder copper block
