## Description of the bug
This is unintuitive and likely unintended. The sprite of coastal/shoreline tiles is 90% water yet resting in it does not extinguish you like it would in a full-water tile. Extremely frustrating.

## What's the difference with what should have happened?
Resisting on a tile that is visually 90% water extinguishes you

## How do we reproduce this bug?
1) Get set on fire
2) Rush to the nearest shoreline tile
3) Die because they don't extinguish you
