Does anybody know what happened to the fill tool? (FIXED NOW)

(Old Post fixed now) Whenever I attempt to use the fill tool, no matter what I do it always seems to find a gap in my lines, and when I try to search for it I never find it.
All you have to do to see the problem for yourself is just draw a shape and try to fill it. this never happened when I used the editor in the past, is this a new problem?
