Is this some weird bug in WORD, or did someone suddenly change the English language while I was sleeping one night
It's not necessarily a bug in WORD or a change in the language. I think it's more the limitations of an automated grammar system versus one where you go through and check every word by hand. I just don't think the WORD program has the capability to keep up with the nuances of the English language. Let's face it, we shift what is and is not "grammatically correct" all the time. I remember years ago that when you were doing a list you had to put a comma after everything.
Mom told me I needed to buy eggs, milk, sugar, and condoms
When I was in high school that was the ONLY way you could write that sentence. Now it's grammatically acceptable to write:
Mom told me I needed to buy eggs, milk, sugar and condoms
I have a similar issue with using words like "Very" and "Really". Word doesn't like me using them. I see those little squiggly lines and it drives me NUTS. I was talking to TeNderLoin about it not too long ago. The example that was given was using the sentence "There was a very big dog" which the article I was reading said wasn't "proper" since "very" is a weak descriptive term. It suggested "There was a monstorous dog". Very big is perfectly acceptable if I just want to describe a dog that is bigger than his counterparts. MONSTOROUS sounds like I'm talking about Cerberus guarding that gates of Hades.
But I digress. WORD does the best it can, but it's just not programmed to pick up nuances in writing. It's not adaptive to individual style either.
