I haven't gotten one to drop in over 2 weeks. I have been running my troopers on autoplay on normal difficulty Savage Reapers in Night City, and it used to be that I could get 1 or 2 to drop per day, helping me to slowly but surely get my purple talismans evolved, but around 2 weeks ago I stopped getting them. Are they just not dropping on Normal difficulty anymore? The low levels on normal are the only ones I feel comfortable autoplaying in Night City, so it would be ashamed if they stopped dropping there. It's been long enough that I just don't think I have been unlucky with the RNG.
