here are a few bugs i have come across.
1. on the Sirius sector black mission where you have to secure 3 locations every time i clear one it wont count it as done. i have done several of them several times.
2. the rubber banding
3. when you leave a sector with a team sometimes the other team members get put in a different instance.
other than those 3 as of now i cant think of any others .
