This only occurs when you use the menus to 'save as', it work about 50% of the time, but if saved document is already opened saving with Ctrl+S works 100% of the time so far.
One issue that does appear consistently is crashes upon document saving either right after opening new document and trying to save it, or after a document has been opened for a while. Upgraded to crossover 18.5 and installed latest office 365 (Version 1902 Build 11328.20158) Excel and word work well, I have not experienced any unlicensed products issues so far as I did with 18.0 (and previous version of 365)
