Thaumcraft 4.1 Warded Jar issue

[LC14199]

Mod Pack: Monster
Mod & Version: Thaumcraft 4.1.0g
Pastebin link to crash log: N/A not a crash
Whats the bug? Duping of warded jars, with essentia in them, or not.
Can it be repeated? hell yes. I tested it on the server with 9 jars, placed them, broke them with a fist, and ended up with 17 jars. Bedrock pickaxes also cause this dupe.

NOTE: Diamond picks seem to be immune to this bug. So break your jars with a diamond pickaxe people!
Known Fix: Not sure if there is one at this time. If anyone can point one out to me, feel free.

Attempts to fix:
1. Destroying all jars known to be buggy and making a fresh set. Still dupes when broken.
2. Client restarts do not help.
3.

It appears after a server restart or two, this bug is no longer happening. mods may delete this thread

In creative mode, Thaumcraft drops the jar item when a jar is punched. It sounds like TC thought the player smashing the jars was in creative mode leading to both the properly popped bottle and the creative mode spawned one.
