Rivervale Pathing
 

(On Green)
Mobs/pets in Rivervale regularly path inbetween walls in atleast 3 areas
-In between docks area and rogue guild
-in between Docks area and bank
-in between Docks are and waterfall
When mobs are fleeing in the water, mobs are untouchable by melee.
When a mob is fleeing in the water, they are able to be casted on despite no line of site
When a mob is killed in the water, it becomes unlootable if it sinks to the bottom.
Pets will run through a wall and warp up to the RV castle and aggro the Sheriff if you're (like me) unlucky enough.
