Some players experienced the removal of missions over the weekend. This was due to an error in an update we pushed out on Friday. The team have since fixed the issue, but I need to manually go in and collect some data to be able to fix this for each user.
If you were affected by this, and your missions have been reset to 0, please leave a comment in this thread (i.e. “This affected me”) and I will collect the data to pass on to the team.
