Update is nice. However....
The appdata folder for Terra Nil has an "analytics" folder and "log" files. Analytics was marked as a threat by microsoft.
I ended up looking at the "log" files and they seem to be trying to contact unity3d.com.
It seems like a large amount of data is being recorded into the analytics as well. Enough to where it was flagged.
While probably a false positive, you might want to look into what is being recorded to such a level it alerts security just to avoid any similar issues later.
