4.18 way slower than 4.15 in Sequencer

Not sure if this is fixed in 4.19, but when trying to animate a robot that I have (a BP with about 8 objects in hierarchy) in Sequencer, it chugs considerably more, to the point that I have to punch in numbers instead of animating using the transform widget. Not sure if there’s any work arounds, but it’s frustrating to say the least.
