i was placing tree resources around my map and i all the sudden got subscript out of range when i clicked save and saw none of the tree resources i placed out are showing up. I did not go out of bounds, these trees were all being placed not that close even to edge of map. here is picture of what i did and where i placed the resources at so you can see, this is full screen and showing entire screen.

in my picture i wrote it happened here but actually it happened after clicking save that was just the very last tree i placed.
