Its mostly that map that the humiliation trap fails to kill him it either needs low hp for hale on that map or the kill damage increased on it.
Or remove it its been on there over a year is there not a updated version.
The most trouble is caused by gaps and glitchable areas in maps that let players shoot at hale primary one is Sawmill final you can shoot at hale from spawn at start if he is low hp kill him, then the trap spots you can shoot at hale.
Familyguy you can jump up on the wall around hales walkway, Other maps have issues too
