after I using the backpack mod for some time, I noticed that I found few bugs, not sure if it is going to be fixed anytime soon.

1, the backpack will disappeared if you die and log out, either with return to title, kicked out the server, or crashed.
2, the backpack is not visible if I use mo'bends mod
3, the backpack hose can milk animania mod's animal indefinitely even though I set them only milkable once every few minutes.

Forge Version: 1.12.2 forge-14.23.5.2847
Mod Version: 1.12.2-1.0.23.23

1. I do not experience this issue, do you use any other mods?
2. It's mo'bends issue, wait for release of Mo'Bends
3. I can't fix this
