I got my game from Amazon and the DLC is junk. Can I delete the DLC? What will happen to my game in progress? Thanks.

You should be able to disable the DLC although this will cause some problems - it's possible this will break your game outright and you won't be able to reload the save without reenabling the DLC. If you don't like the items I'd suggest throwing them in a container and forgetting about them. Then before starting a new character you can disable the DLC.

I think I sold everything but I thought if got rid of the DLC I would avoid some of the issues others are having. Are most of the DLC issues with the Weathered 10mm?
