It happens to me quite often when drag&dropping Loras and Models from one directory to the other. It happens on v.2.12.2, Windows 10.

This is what is shown:

Exception

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')
