This isn't so much a problem right now since there are few group-only missions (is BP the only one?), but it might be useful later down the road.

Add placeholders on the mission board for solo players that show missions that would be available to them if they were in a group.

But instead of placeholder, show full mission headers/intro, with a superimposed symbol and warning stating that mission requires a group.

Many missions, as Hive and convoy ones, can be done both by single players or as group. Probably a line of text should be added to those, stating it can be easier with a group...
