Related but different issue- An opponent played a Naga Fleshcrafter that copied my Guardian, Their copy didn't lose hexproof after dealing me 6 face damage. This resulted in a premier draft loss for me
Exact steps for reproducability (playing via Epic on a Mac):
I had a Karakyk Guardian in play. It still had hexproof
Opponent plays Fleshcrafter, copying my Guardian (legal)
Opponent attacks me with their copied Guardian. I take 6 damage, and believe their copied Guardian should lose Hexproof.
Following turn, I play a Detainment. I am unable to target, as their Guardian still has hexproof
