What happend with underwater loot after HDRP update?

There is no more rock formations like this. Almost summary of ocean’s loot divided by 3
Ocean before was unpleasable place to farm (you spend more time than road roaming to gain equal amount of loot), but now it’s hollow place

Don’t forget to bring back it, when massive update with underwater monuments will come
@Alistair or it was direct decision to nerf water?
