Copper Golem's chest checking is inconsistent and buggy

While testing potential Copper Golem storage sorting systems, the golems have altered the order they search chests in after taking items from the same Copper Chest resulting in stacks of items being split between multiple different chests. They also consistently miss chests for no apparent reason.

In one build with the golem walking over 8 double chests, two layers high and 4 long, one searched the closest top chest, then the closest bottom check before skipping the next column and checking the third closest top chest and third closest bottom chest. Other golems didn’t have this issue but still searched the chests in random orders occasionally.

The Copper Golem needs a consistent pattern, ideally searching the chests in order of proximity, possibly top to bottom then north then clockwise. Even if there is some randomness in terms of what hight or cardinal direction they search first, they should at least check closest chests first without skipping valid chests.
