The option to sell our items in inventory to npc/the game is gone. I'm not sure if this is a bug or new feature. I want to sell the baseball bats I bought for missions lol. 

Are you at the Armed Surplus store? https://cartelempire.online/Town/ArmedSurplus

Selling items is fine here? 

16:07:30 - The shop owner pays you £3,750 for the items.
