Unity 5 - SpeedTree Bug - Wind Turbulence Resets on timescale changes

For our pause screen, we set the game's timescale to 0 and set it back to 1 when we unpause. This has worked well for us until we tried to take advantage of the new SpeedTree feature in Unity 5. We purchased and downloaded the "White Oak" SpeedTree package from the Unity asset store.

We then placed a few of the Desktop quality oaks around, added a wind zone, and started running the game. As expected, the SpeedTrees began reacting to the wind. The issue came in when we paused and unpaused the game. Upon unpausing the game, thus restoring the timescale value from 0 to 1, the SpeedTrees "reset." The branches and limbs jumped back to their original position and ramped back up to the level of turbulence they were displaying previously.

Has anyone else experienced this, know what's going on, and/or has a means of addressing this issue? Is this a bug in Unity's SpeedTree implementation?
