Tell your friend to use the phone APP thing from now on like Lenneth said.
Everyone should if they haven't already, you're even more safe with the token that cost like $15 or whatever.

Secondly, not trying to get on you, but I think you have too many people sitting on thrones.
10 people is too many to have full power like that. At least 3 closest, people should do it, even then that's too much
because you truly never know people lol.

Gutsy could be right and say it's an inside job too just because you have so many people with key in hand.
(You have proof and all but maybe someone there is from Austria? Who knows...)

Situation sucks though. 88 mill is no joke. :/
Hope things work out.
