NBT tag 'Indestructable' disappearing after rejoin (also restart)

What steps will reproduce the problem?
1. Get an item with the {Unbreakable:1} nbt tag
2. Restart the server
3. Enchantments and custom names stay (not tested on other NBT-tags) but the Indestructable tag is gone

Inventories save fine, everything else works fine. It's just this NBT tag that disappears..

Picture:

I'm on Multiinv 3.3.5

Spigot is Spigot fdc1440 - 53fac9f

Worlds loaded and their groups:

Survival group "Ermir":
Ermir
Ermir_nether
Ermir_end

Creative group "Creative"
Creative

My config:

useSQL: true
splitHealth: true
splitHunger: true
controlGamemode: true
separateGamemodeInventories: true
creativeGroups:
- Creative

sql:
host: localhost
port: '3306'
username: blerg, secret
password: blerg, secret
database: blerg, secret
prefix: blerg, secret

SaveInventoryOnQuit: true
compatibilityMode: false

I think this is due to not all data being correctly saved (perhaps into SQL?)

Got a similar problem with Multiinv. I got a modded Server wit TiC installed, when changing the gamemode back and forth the TiC-Items stay intact but when i'm holding the item in the survival inventroy changing the gamemode and then logging off and on, the item is corrupted.

I could be wrong but i think TiC works a lot with NBT and they weren't correctly saved. Would be greate if there could be a fix or even a workaround.
