@Bavionic,
I understand your frustration - but this is not quite true.
We have used the tools and methods provided by Asobo to exclude any trees from appearing on the airport, if the game engine is not respecting such, there isn't much we can further do until Asobo fix the bug.
Again, for both the ILS and Tree matters, we're doing all we can when we can to come to finding a solution since we don't disregard such issues as customers are still discussing the matter actively as being an issue.
I would hope (and yes, as you've mentioned we run on hope here too when there's thus far no possible input from us to resolve the matter) that the next update compiled on the latest patch of the simulator will resolve these matters.
Cheers.
