Unable to retain exp

[DageWasTaken]

Been happening for a couple of weeks now.

When doing missions, I sometimes come out of it and my frame/weapons like I didn't even do the mission. My frame/weapons are back to the levels I started with, despite gaining exp for like 20 minutes.

I also keep getting ERROR 10053 in my chat. I think they're related?

I've observed it for quite some time. To retain the exp I gained, for example in a survival mission, I have to exit before everyone else. If I exit after them or before them, I forfeit the exp.

I hope there is a fix to this, thanks!
