I am not aware of this bug, if any. But I too have come across few forums where users have complained about it. However I tried to replicate the issue you mentioned, but AI behaved well in my case. I rarely use grids, I prefer ‘Snap to Point’ over ‘Snap to Grid’.

I hope this helps. Thank you for the comment.

I have noticed that sometimes even if I have Snap to Grid as well as Smart Guides on, object anchor and/or center points will actually not snap to a center/anchor point belonging to another object. I will zoom in as far as AI will allow and the point I am dragging simply refuses to stay “on top” of the point I am dropping it on. I drop it and almost instantly the point I dropped moves one pixel away to the north, south, east or west of the point I dropped it on. I found many who have complained about this on blogs and forums. Some say it is a well known bug of AI but I am not absolutely sure it is. Have you noticed this behavior before? I am curious to see what you may have to say on the subject.

Thanks and great site btw!
