I think i have a possible cause
As stated above i have world streaming on and although i did not know devices were included into world streaming i think that’s the issue as images below unless the ai being the chickens in this case can and do conform to world streaming
This is the preview grid
Me at the location of the dot in the preview world partition grid outside the load range chickens disappear ect
Changing location so I’m within load distance of the circle - No chickens disappear ect it works as intended
Maybe worth getting the team to check all ai with world streaming tbh this i think is likely the issue
