"something did happen at the end of Hatshepsut reign. Something
so bad that she was almost blotted from history because of it."

Well, I haven't read up on much of her history, but I'm
quite sure I've seen multiple times that her (step?) son
truly hated her. I've read it was considered tradition
for the next Pharaoh to destroy or alter an earlier
Pharaoh's creations, but he took it farther than most
others (which, if I were a man & didn't want the masses
to remember my power was usurped by a woman, I'd
probably try to annihilate all traces of it too).

That is the CW but Egyptians took their history very very seriously. The Pharaoh's were gods on earth. To blot out their name was to destroy their souls. It was the blackest of blasphemies and was only done, IIRC three times and it was carried out by the priests.

Hatshepsut had the priest's full support to take the throne and kept their support almost to the end. They would not have been interested in her feud with her stepson, (who only had the throne because he married Hatshepsut royal daughter, his half sister) Her reign was one of the most prosperous times in Egyptian history.

To rebuild was one thing but this went beyond that to the blotting out of her existence. Something far worse then a family argument happened in the opinion of many scholars.
