When they do a version update they do replace any swapped files. During version updates they do a full scan like with file check, and make you re-download any files that aren't the original matches.
Just to make sure everything is lovely and peachy for their new content!
People who use "FFXI Style" to change the look of the fonts and menus will know only too well about this.
A: .DAT swapping should be just as much of a bannable offense as duping yet they got chewed hard by alot of people.
B: You can .DAT swap to give unfair advantages camping HNM, not as much of an advantage as botting obviously but you can remove darters, manticores, raptors and cleanly target an HNM long before a legit player in alot of cases. Yes, .DAT swapping can be just as unfair.
C: I had darters removed for a long time and i dont think a version update ever fixed it, actually it was a massive pain in the *** to put them back in because i accidentally removed the original file so i had to get someone to give me the darters .dat file over MSN, i tried to put them back in via SE's wonderful file check system but it never seemed to catch it.
