1. I encountered this issue on XBox One
2. I was playing with friends online (all on Cbox One).
3. I was playing as Bruener

After comepleting The Floating City in Crystaline Dreams we get our loot and experience and then are disconnected when we get back to the base camp. This has happened many times. Sometimes one or two of us get loot, sometimes the loot chest is empty. Sometimes we get the experience, sometimes we don’t. Never have all three of us gotten loot and experience. Two of the three of us did not get the next level unlocked (Crystal Harvest)
This also happened on the last mission on Mask of Kelvin, but after playing it multiple times, we eventually unlocked the next level for all three of us.

We would just like the game to work in giving experience, loot and unlocking levels so we can continue the storyline.

We are about to give up and stop playing.
