I have somewhere around 40+ Holiday Epohh tags that I have either dug out of the snow, gotten for killing the giant snowman, or won from the race.
The problem is that I cannot turn them in. Every time I try, every possible mission is greyed out, and I cannot select it. No matter what type of Epohh I choose, whether it is the mint striped one, holiday one, or whatever the other was, I do not get the option to run the duty officer mission. So, I am effectively stuck with 40+ tag that I cannot use.
