While exploring the new caves in the 1.18 experimental snapshot 3, i found a bug that rendered some random blocks as gold ( I thought I found a treasure, or an Easter egg lmao) even though when i mined them they dropped something else, or switched to the blocks it taken over ,since I didn't take pics, I made a video and this is the link for it it, I would've put the video here, but it's too big (48mb)  https://drive.google.com/file/d/1d1sD72zZ7WJHM-kC8Sky4MBt37bkWlf8/view?usp=sharing
