I wish I could say I was surprised by the response. I am not.

They will not respond to 99.999% of Bugs in the Technical Support/Bugs Forum. Which induces rage and frustration.
There is no bug tracking system such that someone could be pointed to an existing bug report and say, "Yep, we know about that. it is not fixed and is not on the current schedule to be fixed. Check back later". Many systems do. Many companies do. CCP (Iceland or Shanghai) Do Not. At least not one that is visible to their customers. Somewhat surprising in all actuality.
I would strongly suggest that you
quit spending more SP on the Skill until the
Vehicle Change Everything And Maybe Fix It Later Patch is added back to the schedule and actually is
Released.
Before I got my SP Respec I had many problems with my SP and the Skill Tree. Now I only have made one or two mistakes. Partly because some of the worst documentation problems are known or have been fixed.
Remember, the core game does not work consistently nor correctly. That needs to be fixed yet it has no actual references to any plans on getting any resources allocated to it, much less it actually being something that should be fixed. New things are being added, many things promised have never arrived, the 1.1 patch drove many away and while 1.4 is the best version of Uprising it is still essentially a broken game.
Which means, fixing your skill bonus problem is so low on the to do list that I doubt if one could see it with the original FarSight Sniper Rifle, back when one could see 1.5km.
As Ever, Good Luck. KR
