People usually ignore a lot of things.
1. Totem in all series, they need to destroy all totems but…..they think these totems just decorations and ignore them.
2. Green Metal Box at one of series, they usually ignore these boxes that need to destroyed.
3. Brown Metal Boxes and Radio Device at final of series, who will know they need to destroy all of these, they ignore them and just stuck in front of tiny house, they should know the mission, but no mission info.
