Extra Data might not be necessary. I will say if it is, and if you need to do it just do exactly what you do to update Deathchaos's dlc. If no wipe is needed, then just delete old dlc, install mine, run the ones you want, and profit. You won't get the characters you already have again, just the new ones.How would we update from the first version of your DLC to the newest when it comes out? I have both yours, and DeathChaos' DLC on my file, then I reinstalled all of the official DLC (except for the Before Awakening one. Having it seems to cause all of the assets on Chrom, Lissa, Fredrick and the Witch to get messed up). I know I'd have to get an extdata wipe, and I think I know how to keep the saves.
After the wipe have you played every single custom dlc entry for both mine and his?No I understand that, what I mean is that after I get the characters from the custom DLC I load the game with the original DLC redownloaded and I get that message when I try to load my save, but it deletes the characters when I load the file. Also what do you mean by "rerun deathchaos' DLC?
