I have been talking to Epic games for the last 2 weeks about not showing up ingame
“Living Weapons Pack:
Adds new in-game missions that, upon completion, unlock three pieces of exclusive, powerful equipment: the Samnu Armor Set, the Danchev AR (Acid Assault Rifle), and the Danchev MG (Poison Machine Gun).”
Epic Games support reaction :
Since you already own most of the content for the upgrade, you won’t be able to purchase it. if you are interested in obtaining the Living Weapons Pack, we would like to let you know that we aren’t able to resolve this for you.
Another great assist from Epic Games i must say after 14 days emailing en paying for a game to them .
Now they wrote go to the Snapshot forum and ask there so here i am is there anybody from Snapsot who can help me ?
The game i love since the last update its so much better en fun to play .
Maybe the only thing thats really sad is using the perk “rage burst” and seeing the Pandorian laughing on the ground because it hits nothing 
I hope someone can help me to get the living pack up in the game its the only thing whats missing .
