I've broken the game even more:
I went back to the dragon after working the pregnancy glitch, allowed my char to be defeated, and after finishing up the sex scene, my char fell through the world. Having no way to stop it (also, it was dark and thundering, so I couldn't see anything), I reloaded the game. I went back to the dragon...only to find that my char is now invincible. In fact, in walking over to a scorpion, the dragon followed me and killed the scorpion instead. It dropped loot...but I couldn't pick it up. I went to attack a wasp, it dropped loot...but I couldn't pick it up either.
I had to exit the game to fix the invincibility and inventory issue.
