this bug is an enormous detriment to the spear. because of the invisible cooldown, lunge can no longer be used as a way to gain a burst of speed to deal high damage.

As of 1.21.9 Pre-Release 2, the issue still happens when the copper golems are checking chests. Copper golems will no longer cause lag when queuing for a chest other copper golems are checking, so my previous example will not cause much lag, but they still cause just as much lag when they are checking chests themselves. I’ll attach a new video with an example

here’s another video. the bug appears to happen when copper chests open near copper golems.

can confirm. copper golems combined with copper chests are ridiculously laggy in 1.21.9 Pre-1

still not fixed. to reproduce in 25w37a, nudge the copper golem to the corner closest to the chest.

This is intended behavior. Copper golem treats matching and empty chests the same way. To prevent cross-contamination, you need to prevent the gold chest from emptying all the way (using redstone comparators to measure the chest). Your suggestion is a feature request.

As i said in notes, copper golems can normally open chests with glass above them. this is not exactly a duplicate of MC-301798, which is about them not being able to open chests under carpets, trapdoors, etc.

(in 25w36a) I am unable to reproduce this. the copper golem checks 10 chests consistently. can you try to make the same same structure elsewhere and/or in different orientations? it could be a locationality or directionality issue.
