Basically, over the last month or so, I've noticed repeatedly that creepers will explode at mobs... without the player anywhere near. I've only seen it happen once, where a creeper exploded at an iron golem while I was maybe 100 blocks away, but I've heard & come across several times where a creeper had evidently exploded at a skeleton, or zombie, or whatever. Pretty sure that's a bug, because they've only ever exploded at the player before. Also affected 1.17, but it won't let me list that version.
