Electrical devices hosted on round columns are being deleted

We have some electrical devices (beam detectors, electric outlets) hosted on a round column from a linked architectural file. Whenever the architect is changing the column family the devices are being deleted from the electrical model file or we are getting a warning that Revit can't place the instances and have to delete.
After some testing it seems that hosting on the circular face is the problem. Anyone came across this issue before? Any fix?

I have had similar issues with curved surfaces. As for your issue, do you have column lines at these locations? Could you host your fixtures to the column line and offset the family? This may require a new family type so that the plan symbol and the 3d element offset.

I have seen this as well. We drew reference planes and hosted to those. Then you can lock the reference planes to the columns.
