Low Mob Routing in Shaolin Temple

Description of the bug: (optional screenshot/video): While attempting to kill mobs in Shaolin Temple, I noticed that they keep getting stuck in certain areas and will not leave those areas, even when being hit. This was only tested on 1-2F, as I did not go deeper into the temple.
What is supposed to happen?: They should route throughout the level they are on, and follow/attack the player if they are attacked.
Where did you find and/or notice this bug?: 1-2F (specifically channel 2)
A step-by-step guide to re-producing this bug (optional): See video

Monsters that can jump often get stuck in certain areas that walking monsters don't. This is just how MS is programmed. (See Parlor, where Anego and Extra Ds can walk the entire map, but Extra As and Extra Bs are boxed in their spawning areas)

 

Well this is every single mob doesn't route so I can pretty much stand in 3 places and never take damage. Don't think that was the intention.

 

Even though it feels broken that they can't go chase you, these 'invisible walls' are one of the main reasons 5-6F isn't completely insane exp. Bishops would probably be able to get 100m eph solo... But you balance maps using janky coding i guess

 

I hope it's kept as a feature because the invisible walls make it the only half-decent minimal attention training spot for ranged characters in late third/early fourth job.
