I can top that. I had done a week-end event for my Roman Reenacting, and I generally carry my gear in a big hockey bag. I found the lorica segmentata fit perfectly in it, and I could stuff all my other pieces of kit in the middle, hollow part of it. Well, I left the bag in my Armoury room, thinking I would get to it and clean it up later to put on my armour stand.
Well, I checked it a week later, and found out one of my cats f**king pissed in it. It somehow avoided most of the stuff on the inside of the armour, but urine got all in the leathers that hold the steel plates together, and caused a lot of rust damage.
I still have the cat, but the segmentata is pooched.
