Skipped ever single mission in underworld to the beast

[Nekroliun]

So...
Yesterday i got to underworld and completed the first place, after i completed it i checked out the second one, to my surprise i could skip all of the battles and go straight for the story in the end thus skipping the whole mission?!? I skipped wrath, and now im in wrath and beezlebub (blood brothers) like wtf?!? So am i going to get banned for utilising this glitch, plz no if i check my mp it tells me that i didnt complete any of the chapters and that i still have battles to complete but i can skip them directly to the story at the end.
It is basically that the story parts are unlocked 24/7 but only in underworld, in bf, kingdom of sands and ailing kingdom it didnt happen, i can even post a pic of some missions and the map if i can figure out how i do that.
Imma cry 93h/perday if i get banned, i dont mind losing the *progress* in underworld or anything ofc, i can barely survive in blood brothers and endgame missions anyways
