Simple before and after illustration pasted link corruption
Hardware: AMD FX-4300 Quad-Core Processor x 2
The bug is shown if this procedure is followed:
1. Using "Copy" and "Paste special" I can create a link between a cell copied from Sheet1 and pasted in Sheet2.
2. In Sheet3 I drag and drop the content of any cell to another cell.
3. Save and close the file.
4. Open the file.
5. Look at the copied cell in Sheet2. The cell has lost the reference to Sheet1 and as a result is now copying a cell in it's own sheet (Sheet2)
attachment1 and attachment2 are "before & after" files.

Not reproducible for me with version 126.96.36.199.beta2+.
I think that the problem has nothing to do with the action on the sheet 3, but that it is a duplicate of bug 86125 and bug 79441
Please could you give a try to version 4.2.8 RC2 where these bugs are fixed?
You can find it at http://dev-builds.libreoffice.org/pre-releases/
Please reopen if that does not fix the bug for you.
Best regards. JBF
