The bug
Copper golems are supposed to only be able to turn into statues when they are very close to the center of their block space. This can be seen in Java Edition, but does not work correctly in Bedrock Edition.
How to reproduce
Place and power a repeating command block with the command
tp @e[type=copper_golem] ~0.4 ~0.5 ~0.4
Spawn a copper golem with the command
/summon copper_golem ~ ~ ~ 0 0 minecraft:from_player_oxidized
Wait a few moments
Expected behavior
The copper golem should never turn into a statue since it’s further than 0.15 blocks from the center of the block space.
Observed behavior
The copper golem does eventually turn into a statue, snapping awkwardly as it does.
Notes
You can recreate this test in Java Edition. The command to spawn a copper golem is /summon copper_golem ~ ~ ~ {weather_state:"oxidized",next_weather_age:2L}
.
