OS: Windows 7 X64

Version Info:
V2.61 & 2.62: No triplicates, only parameters in animation = rotation in a Euler format, animation plays upside down, only 237 frames of animation
V2.63 & 2.66: Triplicates, parameters in animation =rotation(quaternion), location and scale, animation plays OK but only 237 frames of animation
V2.69 & V2.70: Triplicates, parameters in animation =rotation(quaternion), location and scale, animation plays OK with 296 frames of animation

Note that the number of key frames in the older versions was due to a set FPS of 24. This was corrected to 30 already. This bug revolves around the fact that the WXYZ values are getting duplicated in the import on the dope sheet and show up as additional bones on our game engine exporter.
