I had this for a little while not sure what fixed it for me (to a point) I have deleted a couple of folders time and time again (server and Daemon) then verified game files and downloaded them again. I've found a number of animal spawns under water
but since setting up my own dedicated server I've found animals easier to find, Ever ran into a bear while chasing a hare
set to 100 with 60 minute tick, However, tree/crops with 0.5, still not seeing trees grow and I'm sure the crops grew under ground as they vanished from the surface but said 'Harvest' when I right clicked the area.
