What am I missing in my NPC to keep it's joints together?

I recently made a hostile NPC for my game, I believe I have all the joints necessary, but the head will not stay on.

can collide is on for everything and every Motor6D is positioned correctly

looks like a friendly fella
try reconnecting the Part0 and Part1 properties in the “Neck” Motor6D (sometimes studio lies to you and says they’re connected when they’re actually not, so re-do them even if it says it’s connected)

other possibilities maybe, but probably not

• either the Active or Enabled properties in the Motor6D are set to false
• a script is deleting it/causing it to be disconnected (something moving or rotating the head could cause it to disconnect automatically)
• the humanoid is dying somehow, thus breaking the joints
• the humanoid is set to an r15 preset instead of r6 (RigType property)
• the RequiresNeck property in the humanoid

I reloaded studio and apparently I have schizophrenia because it said that motor6d joint never existed.
