as per the title, I updated MB to 2.6 via ATLauncher. There was no indication that a mod (if not multiple, I haven't cross-referenced it yet) was removed from it. I don't even seem to have backups (stupid of me, I know. I've just gotten used to automatic backups I suppose) so that I could revert, reload the world to restore my stuff, close, re-upgrade and add colossal chests back in...
Be careful when updating modpacks. I think I'll need to start looking at the change logs from now on.
It's also "missing" King's Field, Shadow Tower, Sekiro, and others so I don't get your "complaint". The art piece is probably meant to showcase something of a return to form for FromSoft in making games other than Soulslikes.
