Squids rapidly pathfinds on land and kill themself it's not just like evry hour it is enoght to somethimes make like all of the river edge filled up with ink sacks. (I am playing on a realm in survival mode if that is realevant) they also often get stuck in on air so if they are swiming towards the river they come like half a block and glitch back again. It has happend bouth when the server was busy and when just me playiing if that makes any difference

I do not have a screenshot of when that happend because when I discovered it 1.16.2 was right around the courner so I thought you might was gonna fix it then.
