Need a little help with player_ext.lua sprinting

[Sonichum]

I'm trying to implement TTT sprinting (sandbox style), so no stamina involved. I already have the buttons and everything working. The thing I need help with: The runspeed and maxspeed keep resetting every map change. So something is overwriting it as soon as it's loaded obviously. How do I prevent this from happening or how do I automatically re-load the player_ext.lua when the map changes so the speed is how I intended it?

One way I can get it to work is: I change the player_ext.lua and change it back. Then force upload it back into the server. Sprinting will then work. But after a map change it goes back to normal speed.
Thanks.

function plymeta:SetSpeed(slowed)
   local mul = hook.Call("TTTPlayerSpeed", GAMEMODE, self, slowed) or 1
   if slowed then
      self:SetWalkSpeed(120 * mul) --default 120
      self:SetRunSpeed(160 * mul) --default 120
      self:SetMaxSpeed(160 * mul) --default 120
   else
      self:SetWalkSpeed(220 * mul) --default 220
      self:SetRunSpeed(300 * mul) --default 220
      self:SetMaxSpeed(300 * mul) --default 220
   end
end

There is a hook for this, no need to modify the gamemodes files.

TTTPlayerSpeed (ply, slowed)
Server
Called when a player's ("ply") walking speed is computed. The "slowed" parameter indicates if they are using ironsights. The value returned by this hook is used as a multiplier of the default speeds, so returning 1.5 will let all players move 50% faster. Note that maps may not expect players to be faster.

Ah... Awesome. Could you refresh my memory and tell me how to use that? I forgot...
EDIT: doesn't that change the overall walking speed? I'd like sprinting AND walking (hold shift to sprint)

It was. I moved the button. I said everything works properly, the only problem is that the values keep resetting to default, even though they're different in the code.

I think actually I might've fixed it myself. It might've been caused by Spectator DeathMatch or TTT events

EDIT: Yup that was it. So stupid I found it out the same day as I posted this
