Issue with saving a workbook
*Created originally on Bitbucket by [esp198 (Esper Achkar)](https://bitbucket.org/%7Bd8e3fec7-9818-4c7d-a8bb-b1c1f5bfff25%7D/)*
I ran into an the following error on a script I was working on after updating my openpyxl package to version 2.5.14:
"Exception Occured: I/O operation on closed file".
reverting back to the older version (2.5.12) solved this issue.
PS: It was the exact same code I ran in both versions
