So the water is animated, and is 32x32. The Backsplash which will be on a boat is also animated and 32x32 ( the ones you can see ) there is also a 16x32 which goes underneath the backsplash that is visible which is in the red circle, but it is not visible and is under the 32x32 water. My world.icon size = 16 and is causing this issue, i just can't figure out why. If I place the 16x32 alone in null space, it is fine. For some reason it does not like to be placed 16 pixels away when on top of an animated icon.

Memory space saver, and time saver if all my icons were 16x16 would take me forever to map. And I have no problems with the icons themselves as I said in null space ( by themselves ) there is no issue. What I am trying to do is place an icon under the backsplash in the red circles of the picture. The top red circle shows the icon is there, but the bottom red circle where the tile should be, isn't. And also if I made all my icons 16x16 isn't that going backward for BYOND? They made it possible to use bigger sized icons etc for this reason, why break up something 4 times when it doesn't need to be. There is just a flaw somewhere in its codeing, and all I am trying to figure out is how to go about fixing that, or going around it if possible without having to make my 16x32 a 32x32 or by breaking my water up into 4 pieces which also is hard as hell to animate correctly.

So just a question, btw not trying to be rude at all just trying to understand just like you are of me, which seems we are both getting aggravated that neither of us understands the other. Why does my 32x32 water work on top of the 32x32 animated icon, also I have placed 16x16, 32x32 , 64 x 64 , 128 x 128, and 256 x 256 all on a same map without issues at all. My problem is that the off set tile is not showing up , and the map cursor to lay down the icon is not 16x16 it is the same size as the icon so that shouldn't have anything to do with it. For some reason if the icon is offset and not a perfect square no matter the size, it causes problems on other tiles. I don't know how to explain it any other way so maybe someone else can give me some insight if they understand what i am talking about, don't want to waste your time anymore considering you don't.

I just don't get how you are not understanding what I am explaining. But you answered the question regardless the off set icon is being thrown under the 32x32, all I wanted to know is why. I have click to insert instance on but still throws it under the rug. This should not be happening and should be bugged, but in any case i made a temporary solution until i figure out another way, or do as you suggested.

It in fact is a bug, there is no user error for all I have done is used a tile set of 32x16 and placed it over a 32x32 off set. Considering the compiler allows the use of any size icons which is being animated ( remember they added this option years ago for going around the fact to use obj as overlays for anything bigger than 32x32? ) up to 256 x 256. If the option is there, yet it does not work as intended, then that is not user error but the error in the coding through the compiler. All I did was script some line of turf code to be able to place icons on a map, with no error and just labeling the sprites using icon_states, there was no user error at all. Saying that though, I can understand why it is happening due to Ter13's explanation , but it still doesn't meant it is not a bug. If the option to use something is added, yet not tested fully for any scenario, why is that user error? I have been in QA for over 15 years, if I blamed myself for clipping through the wall because i am the one who executed the flaw, how is that logic? In any case, the case is resolved with a simple fix, but it isn't a fix of the compiler. If using the sprites dimensions causes problems like this maybe they should revert to just everything being 32x32 again without the option to make bigger icons.
