I have been summoned, and by using my VASE knowledge of AUs i can concur after looking through many images of AUs i can conclude that this is indeed not Error404!Sans because of there not being lines connecting through the tear marks and as-well as the lack of "Error" marks that is not Error!Sans either, so that means, that must be actual tears, so this is most likely to be TiTR!Sans or just Classic!Sans. Your Welcome.
