They do not have ANY collision which makes them such a problem, you can't destroy them, enemies can't destroy them and you can stack them. You can place 50 at once spot. That is so broken it pains me

yes i know its an issue

the issue is

-- floor lamp
data:extend({{
    name = DLL.floor_name,  -- deadlock-floor-lamp
    type = "lamp",
    collision_box = {{0, 0}, {0, 0}},
    selection_box = { {-1.0,-1.0}, {1.0,1.0} }, 

not entirely sure how to fix it

i have a fix, but it fucks a bit with the graphics if vehicles are on it. (you see the lamp shine a bit trough the vehicle)
