so i have changed the ammount of stone exchange for wood at outpost but visually on the map shows no change and also im only still able to buy 30 how do i change the 30 amount to a heigher amount

For the buying amounts at a time, there is no way to change that as that is a FacePunch restriction they put in place to keep players from farming the machines (however there is a way for players to get more a work around but they have to know how to do it and it only works with the stones and wood. You have to purchase as much stones as you can, then resell it back for wood, now when you go to buy stones again you can buy more. It maxes out at 500 at a time.)

Now for the map part you have to make sure you update the discriptions as well to relfect the changes it does NOT do this automatically.

Example of mine

{
        "_comment": "Sell Stones x 150 for Wood x 2000",
        "sellId": -2099697608,
        "sellAmount": 2000,
        "sellAsBP": false,
        "currencyId": -151838493,
        "currencyAmount": 150,
        "currencyAsBP": false,
        "weight": 0,
        "refillAmount": 100000,
        "refillDelay": 0.0
      },
      {
        "_comment": "Sell Wood x 500 for Stones x 600",
        "sellId": -151838493,
        "sellAmount": 600,
        "sellAsBP": false,
        "currencyId": -2099697608,
        "currencyAmount": 500,
        "currencyAsBP": false,
        "weight": 0,
        "refillAmount": 100000,
        "refillDelay": 0.0
      },
