Goto bug
 

I use goto all the time, and it has a serious problem. It doesn't know when you are mounted.
Even when in the air, if you right-click a spot on the map and select goto, it will zig-zag all over the place selecting flight points instead of a straight line.
If you are mounted on a flying mount, this should NOT happen.

Well, from what I've read here previously, that's a yes and no. Carb will calculate which is faster and route you that way. I'm not sure if the little glitch with Cold Weather Flying with toons below lvl 77 has been corrected though.

So an example with a lvl 80, epic flight, cold weather etc.

You route from Point A to Point Z. Carb figures at your current mount speed it will take 5 minutes to fly there directly in a straight line.

It also calculates that if you fly from Point A to flight path B, then to a final destination of Point Z it wiould only take 4 minutes.

Given that info, Carb will tell you to take the FP to get where you want to go instead of a direct route as it's less time taken that way.
