hm... thats really odd, coz your code looks good. the only idea i have, is to change this

pawn Код:

DestroyDynamicPickup(AHouseData[i][PickupID]);

into

pawn Код:

if(IsValidDynamicPickup(AHouseData[i][PickupID])
{
new debugstring[128];
format(debugstring,sizeof(debugstring),"old pickup destroyed. id:%d",AHouseData[i][PickupID]);
SendClientMessage(playerid,0xaaaaaaff,debugstring);
DestroyDynamicPickup(AHouseData[i][PickupID]);
}

i suspect the cell AHouseData[i][PickupID] contains 0 atm, so no reference for deleting the old pickup maybe?
oh, while browsing the streamer topic, page 1, i recognized the function to change data directly, by using Streamer_SetIntData(). i never used that function before, but its definetly worth a try, you wont need to change the pickups ID anymore, if it works (hm. i assume it will heh)
