Force kick/glitch

My fiancée and I have been playing together on ps4, no problems aside from typical glitches. I bought a majority of the dlc today. Map dlc’s, weapons, companion, motorbikes. Invited her to my game, everything was fine for about 10 minutes. Then she gets kicked. Wouldn’t let her join again. So she invited me to her game. After about 10 minutes she freezes but gameplay commences for both of us. Could recreate multiple times, same outcome. My conclusion was that perhaps, the resistance weapons pack; from my understanding after googling, only the host who has the dlc has the weapons but can drop them for other players. My fiancée somehow had them in her storage as well, now we have continuous problems.
