but they don't specify a map. I've seen this a couple times recently.

loading List.dme
saving List.dmb (DEBUG mode)
warning: world/map_format = TILED_ICON_MAP is recommended for projects created before BYOND version 455. (See http://www.byond.com/docs/notes/455.html)

List.dmb - 0 errors, 1 warning (double-click on an error to jump to it)

Any ideas?
I've seen the same thing.
My suggestion: retile all of your maps' floors.
The value of world.map_format also impacts icon operations, so this is still relevant even if you're not using a map.

I built Deadrons.List library by itself and received the error message. It has no icons that I am aware of. Give it a try? Just me?

I'm compiling a library which contains no map or dmi files.

As Lummox said, icon operations are affected by the map format. It's easy for the compiler to see if you have any icons or maps but a little harder to check if you use any icon operations.

Sure, that makes sense but it's a list manipulation library and as far as I can tell, no icon manipulations.

I just recompiled the library it and it doesn't repro anymore... first time run issue?
