When you join a game that is already engaged, the game don't automatically download and upload right textures on players, what about fixing that ?

Alot of them don't last much longer, and if they do you can just /dl username and /lp 1/0 username

I know there is a command for that, the point is making it automatically.

Yes but what I said meant that, normally the matches don't last long if you join once it's already started, and if it has, you can do those commands.
it really shouldn't be a big deal if the match is going to last that long. I'd rather have players not bug tf out once joining a server half way that be able to see their sets.
