So one thing I've seen discussed frequently here is the accuracy of the text.

However, not long ago, someone made a comment about the Gondor/Rohan/Mordo map having a 'K' spelling on some places instead of a 'C' spelling.

Have there been many (if any) errors on the maps in the past little bit? Is something that's been documented to some degree? I didn't see something mispelt or anything in my copies (that I know of) but would like to check them if there ARE any errors.
