Hi,
I georeferenced multiple images lately and I've encountered a bug-like behaviour every time.
When I add control points it adjusts the map accordingly, but as soon as I save and then close the georeferencing tool, the adjustments from the control points are undone. When I open the tool again, the image is correctly georeferenced again.
When I close and reopen the project, the image is correctly georeferenced and stays like that, which is my (slightly annoying) workaround so far.
Anyone else experiencing this behaviour?
