Hey folks 
 
I have some issues with the boom! and kaboom! trophies - they won't unlock at all. I have destroyed both of them, but still no trophy unlocked at all. Is it something more that I need to do? The description just states "Destroy the blabla"... I also went back to boom! and got it fully synced at a 100% but that still didn't unlock it. 
 
Anyone else had this problem? The first two Leonardo trophies unlocked just fine.

I haven't heard about those trophies specifically, but I do know people have had real problems with other trophies like the pickpocketing and killing a guard with a broom. As in people have counts of like 1430/250 pockets picked and they aren't getting their trophies, so you seem to have that issue. I have the Xbox360 version, and all I had to do was finish the mission, I didn't even 100% sync a couple of them. Good luck man, people are putting this stuff on Ubisoft boards so hopefully it gets patched at some point.

Aight, thanks bud. I'll reckon this is what happens when you only have one year of development time. Such a shame. 
 
After I made my post here I read about people that have trouble getting regular story trophies as well, some didn't get it for sequence 7 etc, which probably means they have to replay a lot to get them later on. Kinda sucks, I reckon I'm blessed that it's "only" a couple of them, hehe
