To give a bit more clarification, the when picked up, the Heroic Space Combat missions work as follows:
1. The mission for the day is available at 6AM CST (4AM PST/7AM EST/12PM GMT/1PM CET/11PM AEDT)
2. That mission is then available at 6AM CST (4AM PST/7AM EST/12PM GMT/1PM CET/11PM AEDT) the following day.
3. If you did not do the mission from the previous day, it will no longer be in your mission log, meaning these are not missions that can be collected and then complete them on the last day of the week. They cycle daily rather than “reset” weekly.
Hopefully this clears up any further confusion.
With regards to reports of inaccuracies in the schedule and the reported bug above, we are investigating and will report when there’s more information to relay.
Thanks for your feedback!
This does clarify how they work, but I have to agree with the other posters that this is extraordinarily confusing and very inconvenient. I would love to be able to collect them all and spend an hour doing them on Saturday, as it is difficult for me to log in most week days. I would suggest switching them to each be a separate weekly, resetting on different days. The net effect would be almost identical, and it would help some of the more casual players get more than 1 or 2 done per week.
