512 Tower

Hey, flatmotion!

Sorry to see any achievement issues. This thread is a bit old, though. We generally suggest posting up new threads so that you can receive the individual assistance you deserve. Since this is still an issue, it seems, let's see what we've got here for you
both.

The first thing we suggest is checking
trueachievements.com. They have a solution for this achievement that I've linked to directly there for you, and states you only need 80 Prismatic Cores to earn this achievement. It looks like some people are complaining about the number counter for that
particular Pylon, so be sure to follow the guides as they state to ensure that you've got them all. If the counter isn't showing, but you're sure that you have them all, they should still count towards your achievement.

If that still doesn't help you out, please be sure to post up a new detailed thread so that we can look into it further. Due to the age of this thread, it will be locked. Thanks for understanding!

I uploaded the same problem mate. Absolutely exactly the same problem that I have.

i have the premium background and no close quarters dlc available

It's not available because you already have it. The 2 gig update last week was the DLC. If you're Premium, you just have to go to the server browser and set the filter to the 4 Close Quarters maps. (Op 925, Ziba Tower, Donya Fortress, and Scrapmetal)

I reloaded the game like 3 times before I found the chest. You can shoot and destroy them. So I was *** myself. Finally ran in that room and saw the open prompt...

Hi sharp256, after the 10/5/2016 update, they introduced a new bug for Pylon 512. Mine also says 2/5 but I know I have 4/4 there. (I read in some other forums that other people have this same issue.) So, I am sure you have all 4, but it is just mislabeled.

As for the objective marker, I found that if you replay a previous story dungeon to the end, it will change the marker on you. For example, I had beaten the game and my objective marker still told me to go back to Eden Tower. I replayed The Warren to the
end and suddenly my marker changed to finding another Pylon or something like that. I think you should just be able to continue to the objective you should be on and all will be okay. I don't know that for sure, but I think you'll be okay.
