Well this is a bit old but anyhow:

they are also cutting off parts of the manga (Bang defending Genos from the Meteor Shards, before taking him and leaping off the building... the Prison chapter, well it was special but it appears canon)

also it seems they are taking parts even from the webcomic (like Saitama deflecting the Dark Matter Thieves' bullets in mid air, which seems to have been skipped in the manga)
