I had a plastic bottle suppressor in my inventory that was in Worn or Pristine condition. You can see it in my inventory, in my jacket, at the start of the attached clip. Towards the end of the clip, you can see when I open my inventory that that plastic bottle suppressor became ruined. I did not shoot through it, take it out of my inventory, use it, or do anything else of the sort. I did get hit by a zombie a few times, but I've never seen this happen where a hit from a zombie ruins an item all the way, through clothing, and nothing else. I tried placing another plastic bottle suppressor in that same exact slot after I noticed that this happened, but after a while, it did not get ruined so I was unable to reproduce the issue.
