If I were him, I would say too bad as well, you signed up for the class, and I'm not going to make special circumstances for you, because then everyone is going to want one. The assignments he gives out can and will change, for whatever reason he thought the class needed to learn more about whatever topic he switched to, so you need to complete that one.
Most students these days are spoiled whiney idiots and think they're special and the rules don't apply to them (not that I'm saying you fall in to this category) so it's no wonder so many teachers and professors are so irritable and hard to work with sometimes. I certainly would not fault you for trying to talk to him, I would probably do the same thing if I were in your shoes.
Knowing the responsibilies you have as a student, you still chose to sign up, even though (I'm assuming) you also knew you would be going out of the country during class. So if I were him I would say "not my problem."
Maybe next time you know you'll be leaving the area you can approach the teacher first and say something like "sir/m'am I will be leaving the country on (date) and I wanted to make sure the paper due on (date) is still correct so I can begin working on it earlier." You mentioned that you talked to him about the second paper, but didn't say anything to the professor about the 3rd paper. Maybe clearing it with him ahead of time would have saved you the trouble.
