Tau Volantis upgrade pack disappeared

I purchased this upgrade, Then lost connection and when I got back on I lost the 3 suits and weapons, but kept the bot capacity upgrade.

My brother, who I was playing with had kept these itmes. He was Player 1 and I was the co-op partner. 

Very disappointed I don't have these items anymore and would like to see them back in my current games inventory

How can I getthis to happen?
