Description
The previous clamping method was setting hitpoints to -16383, so the condition below was passing and hence Natla's control was treating her as already dead instead of initiating the semi-death countdown timer.

To avoid further issues, if an item's hitpoints value is
DONT_TARGET
no further changes will be made to it. For normal cases, we clamp to 0. I've tested each enemy's death, Lara's own death, shooting the scion and the mummy in Qualopec.
