I see that others have brought this up, so I figured I would to. Lost only armor and purity seal as an assault class. Would leave mission multiple times, purchase new equipment then rinse and repeat. Will start a heavy and melee class to see if it is the same bug with them as well. I absolutely understand this is alpha build and so far the game is incredible; keep up the great work.

I have lost all items including both my weapons,  without credits i cant purchase more so can only start a mission unarmed with no armour.  So i am effectively unable to play until fix.  Any news on even a temporary solution?

Exactly the same here. 

I created a new character in order to reproduce if it might be an broken-character issue --> the problem also happened on the new character. 

i'm happy that this game gets patched multiple times a week. so we shouldn't have to wait long for a fix

Global chatter when I mentioned it the other day led me to believe its a pretty common occurrence in this alpha right now, so I'd assumed I'll just have to deal with it until its patched.
