Weird animation bug

I've got an animation that is working perfectly in the animation editor. When I press play on the animation editor it plays perfectly. But, when I try to test the scene, the object is nowhere to be seen! If I pause the test run and go try to locate it, I find that it has jumped to X:0, Y:-49.65351, Z:2.170424e-06 instead of 0,0,0 where it normally is. Then if I view it in the editor it immediately jumps back to 0,0,0 where it is supposed to be. Also it plays perfectly fine when the Game window is not maximized.

What would be causing this? I've been fighting animation bugs like this for 3 days!

Recap:

• Object jumps to X:0, Y:-49.65351, Z:2.170424e-06 when game starts

• Object returns to normal position when viewed in editor with game paused.

• Object animation play correctly when Game window is not maximized.

• Bug persists in exported version.

• Animation is imported from blender.

This thing is driving me crazy! I'm just hoping this bug cropped up for someone else and they've found a workaround. Has anyone had this happen before?
