Well... Why did this happen?

[Smedy]

Just gonna throw in my 5 cents on what might have happened.

Legit version:

Prudent called help, someone zoned in, got the super rare bug where some clients can't see you in the zone or in game.

Proceeded to kill Dafuins which would result in this "unseen hand" thing.

I don't know what triggers the bug, but it has happened to me at least twice on this server, and the only way you figure out that it has happened is when you have a friend in group and you say "why ain't you in my zone" and he says "I'm standing right beside you"

Conspiracy version:

Kringe didn't go out on new years eve and tried his new haxx on dafuins
