Huds appears invisible sometime.. weird :/

[ORDI]

Hello everybody,
i have a problem with my Huds, "They work" but sometime in the server, some huds appears invisible.
i thought i had too many of Huds but nop with only 3 Huds in a mod zom: Money, streak and nade
these 3 Huds bugs often.
However the script Money and streak are the only that i isn't make. I took from killtube when i started to make scripts.

i tried to do some test about it:
1)On all the functions, put:
-thread maps\mp\gametypes\_scripts::money();
-thread maps\mp\gametypes\_scripts::streak();
it dont work.
2)i'm making a thing in menu ingame when it dont work:
6.reload Huds
script:

		if(response == reload)
{
thread maps\mp\gametypes\_scripts::money();
thread maps\mp\gametypes\_scripts::streak();
self iprintlnbold("huds reloaded");
} 
	

i have the message but it dont work..
someone have a idea ?

money script and streak script:

		money()
{
    self.hudmoney = newClientHudElem(self);
    self.hudmoney.alignx = "right";
    self.hudmoney.x = 610;
    self.hudmoney.y = 285; 
    self.hudmoney.fontscale = 1.4;
    self.hudmoney.label = &"^7Money^1: &&1^7$";
    
    while(1)
    {
        wait(0.2);
        if(isdefined(self))
        {
            self.hudmoney setValue(self.money);
        }
        else if(!isdefined(self))
        {
            break;
        }
    }
} 
	

		streak()
{
    if(isdefined(self.streak))
        self.streak destroy();
    
    self.streak = newClientHudElem(self);
    self.streak.alignx = "right";
    self.streak.x = 610;
    self.streak.y = 305; 
    self.streak.fontscale = 1.3;

    while(1)
    {
        wait(0.5);
        if(isdefined(self))
        {
            if(self.pers["team"] == "allies")
            {
                self.streak.label = &"^7KillStreak: ^1&&1";
                self.streak setValue(self.killstreak);
            }
            else
            if(self.pers["team"] == "axis")
            {
                self.streak.label = &"^7DeathStreak: ^1&&1";
                self.streak setValue(self.deathstreak);
            
            }
        }
        else if(!isdefined(self))
        {
            break;
        }
    }
} 
	

And all the Huds are precached.

in .cfg:

set logfile "2"
set sv_fps "20"

developper 0
dedicated 2
