That list of errors represents the opinions of whatever wiki members put them there. It's not some sort of official list. Some of those "errors" might in fact be clues to be explained. Many of them are obviously errors. (i.e. several times when characters speak, their mouths don't move)

And on e goof (the one with Dipper and book 2 in HTRM) was confirmed by Alex Hirsch to be a goof, so yes, they do make mistakes
