Non-DLC owners get those Buy messages when using its content or when trying to take it from the ground or any other storage inventory. I noticed three issues.
- No screenshots/images of Marksman DLC content in those messages, like the Apex expansion has.
- No Marksman DLC logo in tiles that randomly cover the hole screen.
- In the inventory Apex have those green triangle shapes with its logo in it to mark that this content is premium. Now for Marksman DLC, on its content in the inventory, it's just blank white squared shape.
