Could you
- upload your full game log to some pastebin site
- and upload the replay shown in the video to the replay center or to some humane file hosting site
- and verify that this doesn't happen in the 1.8, 1.8.9, 1.11 and 1.11.2 versions (you only mentioned 1.9 and 1.10.2)
- and verify that this isn't specific to shotbow (test it in Single Player and if it doesn't happen there on some other server)
The bug happens in 1.9,1.10,1.11, and 1.11.2. It seems to be fine on 1.8 and 1.8.9. In singleplayer everything works fine, but with multiplayer is messes up. Ill give you the replay in a pm and I cant really get the game log atm as its not letting me somehow.
