I found my first mansion in the new version today. In a small library/private study type room, there were two small tables. On each table were some 20 random bottled / canned drinks, like the contents of a full vending machine. It looks like maybe the wrong spawn type was selected, or a loop was handed the wrong variable for times to roll for loot?
If this is a bug, it’s a bug that has existed for more than a year. I’ve found stashes of vending machine food and drinks in just about every mansion I have ever raided.
