It took me quite a while to realize that I could not get credit for them through campaigns but only with the regular singe/multi player matches. So I was happily just playing through my favorite campaigns normally until 2 days ago
I wonder what is even the point to not allow one to do all the tasks in the same day if they want to… Now the event looks like it will end a day earlier than the time I will be able to get the final task…
I usually do not pay too much attention to things outside campaigns so I was kind of out of the loop.
