[2022] Go to extraction.... Kind of confused. Is this normal, or is it a bug(I mean, It told me to extract)?

I can't say for certain as I don't have all that happened but I imagine one of the 3 players had voted to extract. Then 1 player got KO'd so it left you with 2 players and 1 vote to extract cast so the Extraction countdown started.

Why you were KO'd? I believe you aren't actually on the Extraction pad when it hits zero.
