That's terrifying lol. Im so glad i kept my bank and safe on my character, i kept all my wings and best items in it along with any very hard to find equips. The update is really wuite fun tho. Although i made a mediumcore character for my expert world & its so brutal dropping every item on death lolNot saying this isn't a bug, but I just want to clarify a few details.
Safes/banks are inventories associated with the characters, not worlds. A character can take them to different worlds and have the same items in them, and multiple people can share the same safe/bank on a world and see only their own contents.
If your legacy character did not have "a" safe/bank in its regular inventory at the time of conversion, then there is likely no way to associate the contents of the safe/bank with that character. They are just empty containers on a world at that point. If this is the situation you two had, then this is probably the explanation. The conversion process "forgot" that the character had acquired and placed the safes/banks and had those extra inventories, and it really doesn't involve the worlds at all.
