Srohrer,
I may be wrong here, but it seems to me that perhaps the grounded
workpoints did not move, but the sketch geometry did move. I can see from
the image that the sketch lines aren't fully constrained.
The control points of the Flexible hose appear as grounded workpoints in
the browser. However, if control points are created associatively (that is
using a vertex, workpoint, circular or arc edge center) during creation of
the flex hose, the position of the control point will update when the parent
geometry is moved. So even though the workpoints appear as grounded in the
browser, they can behave associatively.
If a contol point is added to the Flex hose route using "add point", then
it will behave as grounded, and should not move. If a control point was
created offset from a face, it will behave as grounded and should not move.
To fix your situation, create a workpoints on your sketch circle centers.
Next, edit the Flex hose rounte, RMB on a control point and choose
"redefine". Click the workpoint created on the sketch circle's center point
to create an association.
I hope this helped.

I am a two year user of Inventor but a new user creating hose runs with
Inv10 Pro. I just finished routing six hydraulic hoses for a backhoe using
sketches constrained to projected geometry and placing grounded workpoints
on the sketch. After working on the assembly for awhile I noticed that the
hoses had moved from the sketch. The attached file shows the workpoint is no
longer on the center of the sketched circle. What is the point of having
grounded workpoints if they don't stay ground
ed? I have tried redefining the workpoint but it won't let me select the
sketch now. I am at such a loss as to what to do that I am ready to go back
to the old way of using work axis and work planes to make my hose runs.
