Yes Muugen was caught lying.
While he was being questioned he said he didn't send in actions D1, seemed legit right because he was gone a lot because he had his surgery. No possible way he could have sent in the action.
Then when his death was unavoidable he changed it to he did try to disable my passives in D1, which I believe the action was actually sent from the role because I did get the one shot.
That is how I knew they would try to kill me that night and they thought they had my passives disabled, so I told the delve chat that night someone was going to try to kill me. LIkely where michelle caught onto it and healed me.
The only attack that night that came my way was Ekkos.
