Expansion not there

Yes sir, if the leak is true it will work like this I imagine.

Destiny core game:

Expansion 1

Expansion 2

Destiny large expansion:

Expansion 3

Expansion 4

The large expansion is said to have a huge amount of content to justify disc release as well as digital release. Our expansion pass covers 1 and 2.

It's called an expansion pass and yes (covers 2 expansions)

I uninstalled the expansion packs and left the pass installed.

The dark below content still worked because the expansion pass was installed

I was able to play for 4 hours last night and had no problems.

It's too early to say if that is the cause as it just could be coincidence.

But if you own the expansion pass and have also installed the individual expansions just uninstall them as the expansion pass is all that is needed to use the expansions. The individual expansions are only 9MB files anyway. They are probably just unlock
keys and can be deleted if you have the expansion pass installed.

I'll be playing Destiny again tonight so will have to see if it happens again. Hopefully it wont.

it's not limited time, it's an expansion and is permanant for that expansion, it's separate to the main map

What is the code for? If it is for the expansion pack then please be aware that the expansions have not yet been released. The code will get you the expansions free of charge when they are released though.
