[BUG] Find the missing shipment, can not be resolved as expected

[Funreaver]

In the quest "Find the missing shipment" I can not hand over the chest to Zarys directly.
I only get two dialogue options with her, "I saved your men" and "I am still looking".
I have the chest in my inventory AND I have a quest marker over the character carrying the unopened box that says I should decide what to do with the shippment.

Here what i did:
- Found the hideout and got the quest to look for the shippment
- killed the gnolls
- used Karlach to intimidate them from taking the chest, I did not trust them to hand it over and give me credits
- took the chest, both caravan guards still alive and friendly
- went to the Zhentarim Basement with quicktravel
- now can not hand over the chest

From here I have only one option, camp and then the two guards get killed/beaten up but I still can not hand the chest over but have to deliver it myself.
This annoys me as I expected to hand the chest over and Zarys be happy to get the chest and their people back alive...

If I camp and sleep in the basement next to her and return they all turn hostile for "Tresspassing", seems to be a separate issue.

The stupid chest just ♥♥♥♥♥♥♥ vanished from my inventory when I talked to Zarys. I think the whole quest is broken.

Can someone from development or their internal QA check on this, its still broken and while I love the massive patches and improvements latest with patch 2 I would love to continue playing this game once the quest is fixed.

Either please change the journal to not hint that i need to find the owner (despite me knowing the owner because I was told and had the quest to look for the shipment) or let me hand over the box even if the two syndicate members were not able to get home yet.

both guards are dead and i can't get the chest into my inventory no matter what i do.
