Everyone who do it can keep with their loot safe, is it there any fix for it?

Without more information this sounds like a Rust issue.  There were 2 hotfixes after the patch, is this still happening?

Yeah, I think this is rust issue, cause you disconnect then ur character keep sleeping in the middle of nothing, after that you connect and you just go to the coast and thats all. I think one fix could be if you disconnect on the Cargo it automatically kills you or sends you to the random respawn
