Problem description:

Ok this problem occured recently ive been working on my game. i got all the codeing right no problem. now when i go to design the map theres a huge problem. I go to place a a tree and the grass disappears...Almost anything i put down disappears..i even put this code in map_format = TILED_ICON_MAP . can anybody help me?
Don't use TILED_ICON_MAP.

When placing objects, the default behavior is to replace any object that was there before. Hold control to instead have it just stack another object on top (turfs are still destroyed, as there can only be one turf per location, but the old turf's icon gets added to the new turf's underlays).

Better way, go to the map editor and go to these menus:

Options -> Click Behavior

then change the click behavior option to the other option ad you should be fine :P
