Achievements glitched after not being connected to live

Forgot to mention that was all on Xbox One.

Anyway, I found a workaround. I played the game on 360 rather than One and got the achievements that way. The save files started syncing but I backed out because I wasn't sure if that would glitch out the 360 version too. Some saves ported over anyway and
in the in-game achievement screen, only the new achievements I got on the One after connecting to live were checked off, so I was free to get the ones on 360 that didn't get recognized before on the One.

Hey there X Kalomn!

When playing Backward Compatible games you will need to be connected to Xbox Live in order to unlock achievements. When you re-connect they should unlock, but it can sometimes take 48-72 hours for them to pop. I'm glad to hear you found a workaround!

If any other Xbox support questions pop up definitely let us know.

so am guessing you have to buy the most expensive items on the list in order to unlock this achievement.

For this achievement you need to fully mod any car that is not your characters unique car so go out and steal one and fully upgrade it and the achievement will pop.

I pimped out Franklin's Buffalo fully and the achievement popped.

[/quote] I highly doubt that as I also fully upgraded Franklin's Buffalo with everything there was to upgrade but it didn't pop so I looked the achievement up in my guide and this is what is says. "Received upon buying
all available mods for a vehicle that is not Michael's,Trevor's, or Franklin's own personal vehicle". So after reading the I went and stole the first car i saw and fully upgraded it and guess what it poped

The only car I ever upgraded was Franklin's white buffalo and guess what It popped. The guide on Trueachievements.com says "Fully mod a vehicle"...Feel free to check my achievements in the link in my sig.

I used the BF Injection for this achievement.

For me it didn't unlock until I bought 1 Item from each category.... which for me included the paint job..

There must be something a little off with this achievement with so many differing accounts of how people are getting it.
