I Solved this deleting ( erasing ) the tiles just before import , but I dont know if this is the correct way , if someone knows why this happens let me know .tks
Im saving the positions of the tilemap into an array and load into another .
When I load the first time it works with data in array , -1 ( empty ) , but when I erase it , its change in the array , but when I load it again doesnt work with data -1 ? I dont know why ? Only works for the first time
Can anyone help me please
