At 8:40pm EST, playing on server 4247 - North America - NY - 1st person only, I was carrying two bottle supressors in my jacket. I had looked at them both a few minutes earlier seeing they were still in my jacket and I ran through a field and while standing next to a building, i opened my inventory and saw that one of the supressors was ruined. I had not fought with any infected, or taken any damage whatsoever. My jacket was still in pristine condition - the item was just ruined with no explanation.

unsure - I had been carrying these two bottle surpressors for a couple of days inside of a hiking jacket.
