I was also experiencing this issue on Experimental 0.47. Have yet to test on stable 0.47. It was like as if drink all from a canteen made the server die. EDIT: But just drinking 20% at a time worked perfectly fine.

It's not a bug, with the recent experimental update (0.47) you can attach certain knives to your boots (Needs to be military boots I think). Same with the boonie hats, you can attach fishing hooks to them.

Still not working in 0.48 experimental.
