Finding closest tree to harvest can be sometimes a bit off

Issue description

One harvester, three trees marked.

The left one gets cut last, not the top one.

Expected behavior

The two bottom left trees get cut first, the top right one should be last. Kind of "always pick the closest to drive to".

Game version

v0.4.8

We are already serach for closest trees but for performance reasons the search is done via chunks (larger units of terrain). It could happen here that the bottom tree was on a different chunk and thus not discovered.

This was fixed in Update 1. Thanks for your report!
