Did you try to reconnect, if it still there?
Try to go to program files and find mta sa 1.5 files > mods > deathmatch > resources and delete CITphone, worked for me before.
Hi there!The same problem has happened to me many times, I found the solution myself. I just reconnected , it was getting better. But it was repeated a few hours or minutes later. So I solved the solution by deleting the game and not using any modes. That's what I'm advising you.
