What: Trying to individually extract during survival missions (probably other endless missions where manual extraction is possible) and then going in/out of operator mode at the extraction zone will reset the timer to 1 minute.
How: Play survival with other players. Play until extraction is available. Try to manually extract. Wait at the extraction zone for a few seconds. Use transference and the timer will reset to 60 seconds. Wait again and use transference again and the timer will reset again.
This is a problem considering that enemies still charge at you even at the extraction zone. Using operator mode for utility will instead waste your time.
