So I opened the 35 PoE chest and got the shader, emblem, some weapons but not the ship, which was consequently the only thing I actually had an open slot for. My teammate however, who had already received the shader, emblem and ship, received another ship. The only reasonable explanation would be that he received my ship, because I should have got a ship and he shouldn't have but alas this happened. Not too upset about it but if this were to have happened with something more important to the gameplay (ie he got my gear or weapon drops) it would be much more upsetting. Don't know if I'm the only one this has happened to but it could be a problem if it keeps happening.
