So the Hidden Mission Bug has definitely been a major issue lately.
So we can have everyone's reports on it in one Thread, "Please state all the mission's you've noticed are hidden" and also please list down the "SPECIFIC UNITS" you have to click on to find them. The Dev are aware of the situation but need a little more information in order to resolve this issue.
Thank you all for your patience during this time and on behalf of the MissionChief Moderation Team I apologize for the inconvenience you all are experiencing.
Thank You,
Rescue
