So I joined someone for a duplication lobby while I was on top of my Z-Type in my garage. I accepted this invite and spawned in his garage. I had access to every single one of his cars. I took his Weed Van but I couldn't drive it in my garage so I took another car out and drove back in and the Weed Van was in the same slot as his garage and it replaced my car for the van. I have been looking into this and it some people are saying you have to lag switch while joining the game or apartment. I tried but I'm not very good at it(haha). I would like to see this become a new and better duplication glitch. Please help me and others who have experienced this to brainstorm how to make this happen every time. If this is already a "secret" glitch that some people already know and don't want to publicate it please tell me.
