Abandoned waterway facility rocks bug

At first, I was taking like 25 damage per tile of sharp rocks.  Then, for some reason, they were instant death if I touched them, pic-related; those damages are all at once.

Insta death on these floating garbadge as well on my play through as well. I'm playing with max speed.

On a different note, is it really mandatory to keep this damage mechanic in this dungeon ? It seems to me it does not bring much, apart from some not intresting reload.

Rocks block path for jet skis that aren't tanky enough to resist them. They have the same function as slopes which can't be used by a ski that's too heavy/slow.
