The bug is still exists in Realms in 1.11.2. It is really annoying.
Happens regularly on Realms for me. Horse, donkey or mule disappears instantly when I dismount. Appears again after relog.
Are you absolutely sure that this is a duplicate? The whole reason I submitted this was because I didn't find anything similar. MC-6365 is not at all the same as this...
Same thing happened to me, minecart just went away and i were standing still, suddenly chunks started unloading and i logged out. Reconnecting fixed the position, a hundred blocks a way.Other players on the server saw me driving away so i suppose it's a client side bug.
Definitely still occuring in 1.11.2. They might as well remove the ability to tie a lead to to a fence, as it will anger a lot of players that they break or disappear. Honestly one of the most critical bugs in this version. along with duplication bugs.
