Screenshot showing the bug

In Impress and Draw when you add a shape and click it again to enable the "rotate mode", dragging the shape forgets to move the center point. See attached image for details.

Steps to reproduce:
1) Create a blank Impress or Draw object
2) Insert any shape, f.i. a rectangle
3) With the rectangle selected, click it a second time so the "rotation" handlers show up
4) Now move the shape anywhere else
5) Notice that the center point stayed in its original place
6) Try to rotate the shape now. It will use the original center point as the reference for rotation

Expected results:
The center point would move together with the shape, so subsequent rotations would work as expected.

If you deselect the shape and select it again, the center point appears in the right position.

Thank you for reporting the bug. The center point is not fixed to the shape itself instead it is movable, which is not expected. I can confirm that the bug is present in

Screen capture showing the problem

Here's a video showing the problem. Notice that when the user is in rotation mode and moves the object, the center point is not moved together with the image and gets "forgotten".

The bug is still present in LO 7.3 beta 1.

Impress - wrong point of rotation

I can confirm this bug.

There also is another nuance to this bug: If you select one object, rotate it and then select a different object to rotate it, the point of rotation stays on the first object.
I'm not sure if this is unique enough to count as a 'new' bug though. I tested this bug in Writer and there the object can not be dragged around when it is rotated and when you switch objects, the point of rotation switches to the new object.
