Can't see other players cars

When I join my server as first person, then my friend join, he can see my car, but I can’t see his car. But when he joins as the first person, it goes reverse and then I can see his car, but he can’t see mine.

Do this:

  1. save your mods
  2. try without mods if it doesn’t work
  3. go to Beam MP
  4. click “Support Tools”
  5. Clear cache
  6. try 2 first and if it doesn’t help then 3
