So. I earned some heroic souls and held Them for a while waiting for a good rotation. Expecting daedalus, I opened 10 of my stack of souls, red ayes appear, and boom... Assasin hellraiser. Not bad at all, however I was overflown, so it prompt me to sacrifice, so I put the dupes and went on.

To my surprise, guess who was not in my inventory. The assassin hellraiser. Immediately contacted support... 3 days later and no response... So has this happened to you?

Inb4 I sacrificed it by mistake.

No. I triple check all My sacrifices. Unfortunately, that character was greyed out so I couldn't lock him. So it was impossible to fail-save him.

Amy mod can help me clarify what happened? FYI, this was done half an hour after the reset of that day, if that helps.
