As of late I updated my Minecraft game to the new TU 53, with the new shucker boxes and also the off hand slot. When I have died the last couple of days of playing with this new update, any arrows that were in my off hand slot got deleted upon death, as I couldn't find them back several times. I think I may have died something like 5 times, and every time I had arrow in my off hand I couldn't find them back. I haven't actually tested this for the maps that are able to go in your off-handslot, so that might be the same story. This is really annoying, so I hope you will find time to fix this issue.
