Campaing save stats were reseted

Vice versa. I asked you to specify what exactly causes problems

Yes and? Do you think Blizz has meticulously recreated the campaign from scratch in Reforged? I think they just copypasted the whole thing and maybe modified one or two things, which also explains why the RoC balance is gone and overwritten by TFT (they just copypasted the map structures and didn’t take into account that RoC logic still existed inside the TFT folder).

What exactly in those mAp FiLeS and LaYoUtS makes it mandatory for two versions of the campaign to exist? Do you have any programming experience? Just out of sheer curiosity, because you make it sound as if map files and map layouts were some form of arcane or holy entities, for which it’d be obvious to have a different campaign. They’re the same damn files you can create in the map editor as well, just inside a data file so you can’t access them…
