Short description of error
Depending on the cursor location, the snapping points changed unpredictably (to me at least).
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
move the object, or switch to edit mode and move a vertex... change the cursor location and do it again
