After finishing an adventure, i recieved twice the looted goods inside my starmenu.
I was about to write a note to support, when i decided to check a last time by reloading Newfoundland Realm1.

That corrected the problem, which had occured.
Now i had all loots single in my starmenu, as it should be.

Alas still no white-castle.
So we will try Stealing from the Rich again tomorrow.
