Zasaz riddler trophy glitch " Xbox 360 "

[Talzanar]

I done a search and found no topics on the subject so looking for some help here,

When I entered Zasaz's hideout and defeated him, I collected the 2 riddler trophy's that are around his little fort and after leaving, on my map it still claims that I have missed one and regardless of going threw that sector with a fine tooth comb I have found no other missing trophy, I have seen posts on the web of people saying its a glitch that can occur if you have fallen into the water before collecting it.

Frankly this is aggravating as hell, Every suggestion state's that I need to restart the game to get 100% trophy's and that's just not really acceptable considering its the last one I need to get the last set of hostages from the Riddler him self.

Can someone please either tell me a way to get past this or at least let me know that the developers are working on a fix?

I need a solution!

Kind regards

I do not with to come across as impatient but this is really irritating waiting for 2 days for no reply from the entire community? Someone must have also come across this issue? Google it if you need to and see the others who have had it on PS3 as well as Xbox 360.

It's not a glitch, there's actually a trophy you're missing. (there are 3 trophies in Zsasz's hideout).
When you enter the hideout by the vent (with the electric thingy that you have to blow up to get an other trophy), there's a little floating "bridge" in front of you, you must throw an icy grenade on the water on the right of that bridge, the trophy is hidden on the wall. (I hope it helps)
