Achievement Issue in Black Flag.

Hey there, so I've been able to unlock all but one of the multiplayer achievements. Most recently the Level 55 achievement, which didn't pop until after I prestiged and leveled once or twice. It "stealth popped" but..that's not the one I'm having the
issue with.

The achievement I have a problem with is "Personal Bag of Tricks", which is a relatively simple achievement - customize an ability set and complete one session using it. Well I've completed close to a hundred, between sessions with friends, random online games
and so forth...and I've always had customized sets. I've tried all the methods listed in TrueAchievements and XBA guides for "customizing" the loadout but nothing worked. It's odd that this achievement, which should be one of your first, is still having
issues unlocking.

Apparently, as I checked through one of the TA solutions, it glitches for quite a few folks...is there some sort of fix that can be applied on the Xbox Support end? =/ I'm working on completing all these Assassin's Creeds and I finished Black Flag on the 360
a couple years back, now it's the One's turn...except it's been nothing but a pain.

This isn't the first achievement to glitch like this...nah, that was Master of the Caribbean (complete Discovery in Wolfpack). It wouldn't pop for almost a week of trying then finally did randomly...

I've had this issue with Bag of Tricks for roughly 30 days spanned across several months since trying to play through the game. I am not an active Black Flag player so to speak but this one achievement, this Personal Bag of Tricks, should long ago have
popped...

:)

 

AC4 glitched achievement - naval contracts

Achievements still glitch in Black Flag. I have two that aren't unlocking. I doubt this will ever be fixed due to a lack of communication between devs and Microsoft on this particular issue. Humph... oh well.

 

Achievement not unlocking...

It's happening to me on black flag lol kinda *** off hopefully they fix this achievement problem!!!

 

Is there any fix for this? I have tried so many things since I last posted this and still no success. One guy who had my issue said it finally unlocked for him later on but he doesn't know what he did different. As one of the easiest achievements in this
game it's proving the hardest to unlock =/
