After playing for a long time with my game, got a "ghost" object which isn't there but, somewhat, is still there o.O
I load the save with the debugger, identify the object (an animal), and realized it has both X and Y set as non numbers (NaN). I'm baffled by this as i have no idea what the heck happened and how that damn triceratops is in this situation.
So what i'm asking is if there is a condition that allows me to check if an object is in "NaN" X / Y, so i can at least catch the bug the very moment it happens!
