This is an intended change that adapts tree farms to the restrictions of natural world generation and removes the overlapping by tree farm trees. This should be done by the trees actually dying instead of a message, but that was not an option for a quick fix - which was needed as tree farms as done before cause severe performance issues for anybody nearby.

You can change the value "MinTreeSpawnDistance": 4 in EcoSim.eco in your server configs folder if you want to change the behaviour, but this is on your own risk and your game might be considered modded for any issue reports about performance.

In the future this restriction will fall and be replaced with a natural approach as mentioned above and the distances will be reconsidered then as well to mainly fulfill the purpose of having a distance that makes sense for tree growth.
