As i found an empty Med-Kit, i added it to my Backpack, to stuff it with my yet collected medical Supplies. I tried to put something in it, that didn't work. Then i tried to show Contents and saw it suddenly being full, so i switched the damaged parts against my pristine Stuff and left the Rest behind.

Server went restarting.

I chose another Server to play on, just to see, that the Med-Kit was missing in my Inventory AGAIN! Also all of the contained Goods were gone. That left me with only 1 damaged Rag remaining instead of 2 x 100% pristine Bandage, 12 pristine Rags and a pristine Splint.
