Unable to designate some trees for cutting

Issue description

I'm playing on the Armageddon map after v0.7.2, and I'm unable to designate some trees on the map for cutting. When I use the designation tool, tress around the affected trees are marked for cutting, but specific one are not. These rouge trees still block buildings from being placed, which makes building larger buildings, like farms, very challenging.

Here is a video showing the problem: https://youtu.be/nryyz-gVzqI
The save file from the video is attached.

Reproduction steps

1. Load the attached save game file.
2. Attempt to designate either the single tree directly above the farm, or the group of trees shown in the video

Game version and build number

v0.7.2

Operating system

Linux

On further investigation, this seems to be a visual issue only. I unmarked all trees and then dragged the designation rectangle over the tree that wouldn't highlight. Even though the tree was not visually selected, the tree harvester rolled over and removed the tree.

This was fixed in one of our previous updates. Thanks for reporting it!
