Characters not loading upon joining?

Hi, basically in my game I have been encountering this problem where if I join or any other player joins it seems, if there were people already playing the game, their characters dont load. What i mean is that they are invisible, they dont make sounds, you cant see the tool they have equipped or anything. The only way to fix it is for the invisible person to reset their character. Obviously, this is very bad. I have noticed, however, that this only occurs if the people already playing are NEW players. I don't really know what the cause of it is but this is the script that loads when the player joins the game, in serverscriptservice. Help would be much appreciated!
