One mission story on Santa Fortuna related to Jorge Franco can get bugged. Spoilers ahead!

Obviously spoilers for people that haven't played the Santa Fortuna mission from HITMAN 2, but I discovered something interesting. Spoiler text ahead, read at your own risk.

If you go for the "Half Baked" mission story and arrive at the coca fields. After you do all that's necessary and have to start Jorge's machine something interesting can happen. If before that you subdue the guard on the south entrance of the house where Jorge's machine is located you won't be able to complete the challenge associated with that mission story, killing him by pushing him in the machine. When you activate the machine and Jorge asks the guards to escort out the people that work in that house that guard you subdued is the guard that checks the place and tells Jorge everything is clear. If he is subdued that sequence doesn't happen and Jorge just stands near his machine and doesn't move. At least he didn't move for me. After I loaded up a save and spared that guard everything went fine.

This frustrated me a lot since I was sure I wasn't doing anything wrong, but it just happens I did this one thing that broke it unfortunately.

I feel a lot of missions can be very buggy like this. The barber mission in Mumbai had the target ignore my barbershop. 4 men were waiting including him, I chose someone else, and he never went back in queue again

Likewise the unveiling mission in Santa Fortuna ruins a SA ranking because the body is found after you drop the statue on it, even though accidents shouldn't count towards that

I think when doing missions, it's best to touch as little as possible and don't use them as means to get SA.
