Looks like the new patch cooked the severed head glitch. Apparently the “Shinnok’s amulet” glitch is still a thing.

Checked my kustomization screen and krypt, looks like everything I unlocked, remains. Woot!

I just got Raiden's and Kollector's severed head naturally. I did the glitch but now I feel bad about it. Not only it wasn't worth it rewards wise but it looks like I wasn't that far to do it naturally. Would've felt a lot better.

Actually no. I just got Frost as well. Now I think they might have changed it to less than 50. Or it's just a coincidence.

i missed the 10 heads on the other side and they patched it the next day :( Im not sure if doing 15 heads unlocks another one of the doors in shang tsungs throne? I want that flaming chest EDIT: i found a youtube guy showing all the locations and as I thought, all 3 door in shang tsungs throne are still closed. I need more than 10 heads probably to open them as I have 10 heads already.

Good luck. On PC the patch wasn't out yet so I could glitch it, hahaha.
