No Mither Rework
Keep No Mither how it is with the exception of two simple concepts:
The survivor starts out healthy
The killer cannot see the broken status effect... just take that off the survivor indicator all together at the bottom left of the screen. Have it be an indicator like Mangled, Exhausted, Etc. Also, for other survivors, have a red perk indicator (similar to Thanatophobia) so other survivors know that they are near a No Mither survivor.
