Perhaps someone can confirm for me that with Microsoft Word 2016, -there has been no change in VBA.
Do all the same old commands still work?
Is all the old syntax still the same?
Any changes I should know about?

If there are no changes in the 2016 version;
I have another theory. I think some settings changed with the Office 2016 Reinstall.
These settings affect whether a space gets appended when pasting from the clipboard.
....Because I noticed that now, some of my pastes get truncated because I must allow for spacing in my Word Document.
To make a long story short, I have to change my VBA code to work with these new default settings, most likely.
....Then maybe the other problems will clear up??? I don't see how.
