If you cancel Origin Premier and buy the standard edition, you will not have access to the LoD cosmetics. I now have an issue where the game crashes when trying to customise my javelin because the LoD paint is still there, but un-equipable.
@LunarBear8 I had the same issue, at first I uninstalled Anthem fully. It didn't work till I crashed once, restarted my PC. Then finally It is running just fine for now. It seems the only way to fix it is by fully re-installing the game. Hope this helps.
