So, let me be fully clear here, then:
I received an item last night which allowed me to roleblock a player. I used it on Heiter and no kill occurred. I suspect this was the source of the blocked kill last night. I do not know who gave me this item. Do not claim it if you did.
With my role itself, I also targeted the living player with the most votes yesterday (a random player if there were multiple tied for this position), which was pandora. I will not disclose exactly what happened to avoid anti-claim.
The result here: if Jarek is telling the truth and my item was successful, then pandora’s claimed information is false.
If pandora’s claimed information is true, then either Jarek must be lying or my item failed due to roleblock immunity and the kill was stopped by something else last night.
