Entering an online session may sound enjoyable but beware for the increasing modders, they can attach certain objects to your character which can be a pain to play with. Here's a good way on how to get rid of the objects:
Kill someone/get killed so they/you can send an invite to an 1v1 deathmatch. Let them kill you once and it should free you from the objects.
Cons: You will be able to hear the entire lobby once you've entered the deathmatch, you'll have to mute the other players through the player list.
