anyone know what causes this runtime error?
runtime error: bad icon
if(IS in icon_states(usr.icon))

it happens on the last line of that code
it happens randomly, and it seems to happen on just about anything, mostly players though
i added those 2 ifs to try and fix it! but no luck
IS should be the name of an icon state
i wonder if it could be happening when IS is null o.O
hrmmmmm, any help would be apreciated!
In response to Falacy (#1)
also this happens in byond 3.4, 3.5, and 4.0
try: icon_states(icon(usr.icon))

otherwise, show me your entire function. You may not want to be using usr here, as it may be null in this context.
