The second part is not a glitch, that's a conscious design.
I wanted the rewind to be a full reset of the enemies, including their chase mode, because it's annoying when you have a monster chasing you and it never stops even after losing track of you. Kind of like in infiltration games, where if you hide, the enemies will end up going back on their scheduled way.
Glad you liked it, and sorry about the collider. As already said on other comments, it'll be fixed this week end.
