I found 3 suspicious gravel that dropped no loot when I brushed it that generated naturally

Coordinates: /execute in minecraft:overworld run tp @s -2747.83 68.00 1101.67 -1676.11 -0.13 (i think this was the right structure, it might have been one of the adjacent ones. Let me know if this doesn't work.) (Also yeah the ocean ruins are really far from the ocean Minecraft can be weird sometimes )

This does not work consistently. I ran an old backup of the world and went to the same place and the suspicious gravel was there as normal. It seems there's only a tiny chance of this happening.
