Piglin Brutes don't attack without line of sight after they notice a player. If a zombie is pursuing me and I hide behind a wall, it will still try to get to me, but this is not the case with Piglin Brutes unless you punch it. They also don’t get angry when I break gold blocks
This report is invalid because you reported multiple issues. The second issue is intended behavior per MC-193188. The first issue may be a bug with zombified piglins, or it may be a bug with other melee mobs, or it may be intended- it’s hard to say for sure, I need to do additional research on this.
