Bots chasing players

Bots are chasing my players well beyond the deaggro range I have set of 50 meters. One bot chased a player home 2 grids away from their monument. What can I do to fix this (or potentially encourage it)?

This was a scientist that followed my player home. Blue hazmat, mp5, and very determined. haha

A player rode their horse home from looting water treatment 2 grids away. A minute later a bot showed up and began shooting at them. I was nearby building a bridge over a river for grins when the bot aggro'd on me when it encountered the player's external stone walls. 

My biome wandering bots have a different outfit, and water was the nearest monument. :shrug:

Makes me think....
5 nakeds with DBs and a agro range that spans the entire biome = Doorcamping bots..... right XD?

I pity the oak that wanted to play alone for a while....
