1. Open Game Master - Spawn an AI - Right Click AI - Take Control - Test the 'Low Ready' keybind (Works)
2. Open Game Master - Spawn an AI - Right Click AI - Edit Properties - Adjust blood until unconscious - Save and close - Adjust blood until awake - Save and close - Take Control - Test the 'Low Ready' keybind (No longer Works)
3. Test with other characters, keybind now seems inconsistent and fails to function half the time on keypress even when playing as different AI.

Alternatively:

1. Open Game Master - Spawn an AI - Right Click AI - Take Control - Test the 'Low Ready' keybind (Works)
2. Crouch - Stand Up - Test the 'Low Ready' keybind (No longer Works)

I did notice that once the player wakes up from a downed state, sometimes in the bottom left will appear 'Put Away' with a UI symbol for Left Click.

From doing more testing, it seems that the Low Ready function stops working sporadically when playing / doing random things (after placing bipod, going prone, crouching, switching character, shooting a few mags etc)..
