Some team mates and I noticed that sometimes we end up spawning into maps somewhere between 18:00 and 22:00 instead of at 25 minutes minus our load times. A player came on to Discord earlier to ask about it and it was apparently confirmed by [SIG]Mett that it was a bug.
While I'm not a fan of being delayed by 20-30 seconds just because of loading times I actually like loading in several minutes late, and having other players load in late. It means you might encounter a fresh team when you've been in a few fights. It means you may encounter player ships on your way out of the map. You might also end up running into someone trying to exit an airlock AI ship, or sub-raid location just as you're coming into the map or just as you enter those locations. It adds variety, and tension, because even if you think you have ended up in a raid, ship, or sub-raid alone someone else could come in 3 to 5 minutes later.
This might be a Starsiege Tribes moment for Marauders, and just like skiing was a bug that was so popular that they kept it maybe the late starts are, too.
