Infinity Time Bug/Glitch

So I have Origin Access, and my 2 other friends don't. So we were playing Garden Warfare 2, infinity time via the zombies with the cat. While playing the "Nemesis" wave would approach and we would defeat all the gardens, while finishing off the remaining foe it said, mission failed, but then said objected completed and +1000 coin. On top of that the next wave started with the remaining guys still there from the previous wave. Eventually we lost. Dumb. Tried again, thought was just a glitch, then same thing happened. Reached the 2nd "Nemesis" wave and defeated all the gardens and looked for more, none, but failed but objected completed +1000 coins. Then while continuing to play, my 2 friends and I were doing well, roughly wave 24ish and then 2 of us got disconnected, no money/loot, or ability to re-join or open a chest. This is unacceptable. Please fix or help. Thanks.
