Copper chests of different oxidation stages (and waxed variants) incorrectly merge into a single large chest

Steps to reproduce:

1. Place a small copper chest of one oxidation stage (e.g., Copper / 1).

2. Place a small copper chest of a different oxidation stage next to it (e.g., Exposed / 2).

3. Observe that the two chests merge into a single large chest, instead of remaining two separate small chests.

4. Repeat with other stage combinations (2 + 3, 3 + 1) and waxed variants — the same issue occurs.

Expected result:

Small chests of different oxidation stages (or waxed states) should remain separate when placed side by side. Large chests should only form when both sides are the same stage and state.

Actual result:

All combinations incorrectly merge into one large chest, ignoring oxidation stage or waxing differences.

1 = Copper

2 = Exposed Copper

3 = Weathered Copper

4 = Oxidized Copper
