My achievement is not equal to that of Bioware. I miss two unlocked on 09.03.2012 please look at my Xbox account. It's about "Freedom fighter" and "Prothean Expert". It's not possible to get this achievement two times.
I second that. I got both achievements unlocked in my Xbox Achievement list, but when I look at my ME3-achievements within the game, both are shown as not achieved yet. I thought I'd be the only one with that problem, but it looks now like a bigger bug.
I got this bug too. It affects Striker, Freedom Fighter, & Prothean Expert. A temporary fix is to load a save where you have achieved these (like a save where you already have Javik in your party) then go back to the main menu where they will finally show up. However, you have to do this everytime you start up the Xbox.
Thanks for the temporay fix. But in the end it doesn't really change anything. For me it's more important, that the Xbox achievements are correct, so that I get the full score plus the different display, once I have achieved ALL achievements for ME3.
I am just disappointed by the huge amount of bugs and glitches I keep discovering still every day. And then Bioware claims to have fixed at least some of those, but they still continue to happen (like the famous vanguard glitch, where you are going to fall through the map at some point).
Is it really that hard to reset the three-dimensional values for the position of the vanguard?
And there are so many other little bugs like your ammo suddenly displaying a negative value of -1. Or a weapon like the crysae sniper rifle only allowing two shots instead of three although your magazin is nearly full. Sometimes I wonder if they can't keep those little things under control, how the game works at all. :-)
I've got an issue rather similar to this one, but it seems fairly random: Sometimes I'll have all three of those achievements showing, sometimes just one, sometimes another, sometimes two or all three. Kinda annoying, although not a big issue. I would have thought it fairly easy to fix, though. Once you get an achievement, it gets nailed down. No rechecks or anything, just "done".
