Cyberpunk 2077 1.5 (PS5) - Lizzie location
Lizzie is an iconic tech pistol, that always spawned once V talked to Judy in her den after the Automatic Love quest started. The gun always spawned on the table next to the door to the den (or out of it) and V could only grab the weapon there. If V missed it, they couldn't grab the gun later afaik.
In 1.5 the location of Lizzie spawning changed, and apparently you can grab the gun even after you left Lizzie's bar, i.e. you can go back and grab it (possibly) anytime after you've talked to Judy.
I tested whether the gun spawns even before the Heist quest, and although the room is open when Evelyn takes V to meet Judy for the first time, Lizzie does NOT spawn there, and does not spawn there after the braindance either. After that the Judy's den is closed until the Automatic Love quest starts, so Lizzie is obtainable apparently only after V talks to Takemura in the diner.
