Players of Combat Patrol frequently refuse to exfiltrate despite all enemy AI being killed. Often they do not understand that they must all be at the Exfiltrate objective in order to end the mission. This can be mitigated by adding a dialog which lists which players are outside the exfil point in the same way such a dialog exists in the Apex campaign.
On official Combat Patrol servers, which are frequently patronized by players who only understand languages other than English (e.g. Chinese, Japanese, Russian) it is not possible to mitigate this behaviour by voting for a restart or voting for an admin as it is impossible to muster enough votes.
