Angried zombies causing server drops if all of them looking for survival or just trying to catch him.
Its not a big dill if you are going to fight with one of them. But it's gonna be painful for server and survival exp if all of them saw you. Sometimes it's just unplayable (difficult to shoot them, sometimes it's even problematically to close the doors).
It seems like the castle at this location a little bit broken. Zombies doesn't understand how exactly they should punish the player and sometimes getting lost - if you are gonna hide in the camera with metal doors so they are going to outside (idk why but its seems logically for them). They don't wanna wait for you near the doors even if its so close to you.

Another moment at this location and also related to zombies. Zombies doesn't care about grids in the castle. They can run through them
Maybe we should check this problem at cherno too. But I'm really hoping it was useful for you.
