llOverMyLand not working for groups?

Hello there. For a gadget I am about to release, A server needs to check if a key is over its land. This is all very easy, until it is on group land. I have tried deeding the object to the group of the land, and It still will not detect that the key is on group land. (When it clearly is)

Is this function broken, or am I doing something wrong?

I just went in world to test and make sure. It does work if the object is deeded to a group and over group owned land. The wiki says it does as well.

integer llOverMyLand(key id) Returns TRUE if id is over land owned by the script owner, otherwise returns FALSE. This also works for group land, assuming the object is deeded to the group. It will not work if the object is not deeded, not even if owned by a member or officer in the group. The object itself needs to be deeded.

Maybe you should make sure u didnt just click share with group, you need to click deed to group as well
Here is the code i used to test it:

default
{
    state_entry()
    {
    }

    touch_start(integer total_number)
    {
        if(llOverMyLand(llGetKey())==TRUE)
        {
            llSetText("TRUE",<1,1,1>,1);
        }
        else
        {
            llSetText("FALSE",<1,1,1>,1);
        }
    }
}

You can use llGetLandOwnerAt:

 // Get key for land owner at object's current position:
 key GroupKey=llGetLandOwnerAt(llGetPos());
 
 // To check if a detected key is over the group's land, do this:
 if (llGetLandOwnerAt(llDetectedPos(0)) == GroupKey)
 {
 //Do something
 }

This should work both on group and private land.
