Started up the veil of ancients voyage and proceeded to clear stage 1 (Belle), and stage 2 (shipwreck graveyard)
I completed both stages and brought all loot onboard my ship,
I then sailed to the nearest outpost where I slotted in the 2nd veil stone to initiate the third stage (fort fight)
I saw the fort was on the other end of the map and cancelled my voyage.
My loot which I had put on my boat from the shipwreck graveyard disappeared, but the loot I gained from Belle's quest remained on deck.
Possibly a bug or error from the fix which was implemented to stop people from abusing the shipwreck graveyard bug.
