Uncharted 2 bugs

Nothing against this game, it has been fantastic!! I did however come across a few bugs that were VERY frustrating. I had all of the medals for the weapons kills unlocked along with quite a few other and for some reason when i loaded the game later that day they were gone! the only thing i can think of is that i didn't have internet connection at the time i got them and then the next time i started up the PS3 I did have an internet connection and maybe something was overewritten or something i don't know. the good thing is that i will still have fun earning these medals again! :)

I also found a few glitches (mainly out of map in campaign) and I'm working on putting together a video with tutorial.

great....GREAT game. It's a lot of fun and was the MP experience I've been wanting.

On a different note, Uncharted 1 is still pissing me off. I defeated the game twice now and my trophies still are not posting!!!! Anyone else had this trouble???

edit: added the photos of the glitch
