Trophies questions (bugs ?)

[Ashesheart]

Hi,

 

i'm currently on this game. I have no problem with the story mode. I've got all trophies (except one but i didn't try a lot of times).

 

But i've got problems with some trophies of the rescue mode : 

• UFO Hostage Missions (Unlock all 4 hostages in the UFO in Rescue Mode) : i've rescued all chicken, 16 of them + Hardboiled !
• The Road Less Traveled (Unlock Hardboiled Chicken for Rescue Mode in the game) : i've rescued Hardboiled 

Here's what i did (in this order) : 

• I've rescued 4 hostages on Putzki Castle => Castle Hostage Missions trophy pop
• I've rescued 4 hostages on Putzki Porc Plant => Factory Hostage Missions trophy pop
• I've rescued 4 hostages on Jungliana => Jungle Hostage Missions trophy pop
• At this point i've got the 9 artefacts (in order to open the gate to the UFO location, the fourth and last location)
• I've rescued 1 hostage in the UFO 
• Then my boss told me that i have to rescue Hardboiled 
• I've rescued Hardboiled => no trophy (i suppose i had to get the The Road Less Traveled trophy no ?)
• I've rescued 3 more hostages in the UFO => no trophy (UFO Hostage Missions)

Any idea please ?

 

Thanks for all
