I sent bug reports for the Mk108 30mm dmg bug (on bombers) on dec 2013 first, and its still not fixed, so your tree bug...

then.... odds are it wasn't a "bug". I have full faith in HTC's ability to check and correct legitimate "bugs" sent their way.
For instance, a few years ago I sent video of a M4/76 taking out my Panther from 2800 yards away to my 12:30-1 O'clock. The hit came in and hit my chassis at track level, along the right side, at such a shallow angle that any tank round should have deflected, regardless of caliber. Not to mention busting through the track on top of it all. The next update it showed a "fix" to an armor bug on the Panther. Case in point, don't necessarily expect HTC to hand out cookies for showing a bug, or even a get "thank you".
Submit your "bug", then keep calm and carry on.
Again... the tree is an object in AH that needs to be contended with. Learn then, respect them, deal with them. Suck it up, cupcake.
