More specifically:
' tried to become \'
\ tried to become \\
Because the excess \s were never cleaned up, the first apostrophe would give you one slash in the comment, then you didn't even need to change anything at all and any update in the same game would give you 3 slashes in that comment, then 7, 15, etc.
Now an apostrophe is shown as \', but the slashes no longer inflate exponentially. It looks choppy, but at least you can live with it.
