only thing I can come up with for getting unexpected row sizes is if you are trying to use a dbc file from another version or expansion of the game on a version it didn't come from. if thats the case, there is your problem.what are you using to edit your dbc files? secondly you're not really clear in what you're referring to replacing.... are you making new textures with something like photoshop? or are you just trying to re-assign stuff?if no one answers you, it's most likely because no one has a clue and because your post was pretty vague, there's not much to go on either.
