Description of the issue:

Sometimes the Engineers Toolbox will delete its inventory, I have noticed this behaviour happens especially if you transition from Survival to Creative mode either with it in your inventory or if you open it while in Creative mode after changing your gamemode.

Crashlog:

No crashlog, and nothing happened in the server logs,

(Haven't tested in local IE only instance as I am not entirely sure how it happens.)

I've just had this happen on 1.12.2 with the enigmatica 2 modpack.
Steps to reproduce:

• Insert item into toolbox
• Place toolbox inside enchanting table
• Remove without enchanting (can't be enchanted)
• Items are missing

Have not seen reports of this on recent versions. Closing this, as 1.14 is no longer receiving updates.
