"/unstore" causes damage to items

On Enigma V.4 ATG we use the older non-plugin-version of Flak-FlHook 1.67 Build 19 and stumble into a strange oddity:

The user-commands “/store” and “/unstore” work pretty good, but there are specific items (example: cloaking-devices) which show a MINOR DAMAGE (costs of repair: 1 or 2 Credits) EVERYTIME the Item gets UNSTORED.
Sometimes the same issue appears when it comes to the command “/bequip” or similar commands like “/bammo” on those items.
Huh ??? Minor damage on the recently crafted items ???
Maybe this sounds familiar to someone…

The problem is:
If you “/unstore” such item and try to trade it to another player, the trading fails/gets interupted due to the damaged item.

Anyways…“/transfer”-command works even with the damaged items so there is no need to rush for a solution, but I would like to ask u folks for suggestions or maybe a fix for this…

The minor damage occours on the items (only some… like cloaks).
