@Tux2 Thanks alot!
We are all struggeling with missing NBT tags after some world changes or relogs. Seems like MultiInv doesn't save NBT tags correctly.
For example:
- A player got a heal-potion and logs out or changes the world. If he come back after a while, it turned into a water bottle. Till MC 1.9 there wasn't a problem, because potions haven't used NBT before this version.
- In my adventure world I give my players armor with the "unbreakable" NBT tag {Unbreakable:1}, so that the armor can't be destroyed. After relog, this tag is gone and the armor starts breaking.
- Banners are very often empty after relog.
- Mobspawners (Zombie, Creeper, Skeleton, ..) randomly turning into pig spawners, probably also because of missing NBT data.
- I'm running a plugin called ElytraPlus, where the elytra gets a NBT tag so that you can use it like a jetpack. Also this tag will be cleared after some time.

In other points MultiInv still works fine and is one of the best inventory management plugins, also in Minecraft 1.10.

Potions are fixed in the latest beta version, thanks!

Wel command blocks with NBT data chest with NBT data. links, events, hover, etc in books, gets deleted. Should I continue or does 

Should I continue or does the point of no NBT is finally getting though? this was reported above by Bronzeteufel on Nov 12, 2016, and now it still hasn't been fixed! like wtf?

I heard it loud and clear. This plugin has definitely outserved it's usefulness as the NBT data structure inside of items has gotten too complex for it. Because of that I have had to make the conscious decision to only access what is freely available via the Bukkit API. If you want exact clones of your items, including the entire NBT data, you might want to take a look at MultiInvPlus on Spigot.
