So I just found out, after searching for it online, that when your homestead chest is full, all items you send to homestead will be deleted without warning, notification or any prior mention of this mechanic.
This is also the case for quest items, allowing you to break the game while you think you're sending the important stuff somewhere safe. Hasn't happened to me yet, but if I didn't go searching online for where all those missing items went, it would have eventually. Silly me, thinking that with all those scores of containers in my homestead, they must surely turn up somewhere.
And no, it isn't *HARDCORE!!11!lol!1!*. It's game breaking.
So I view this as a sort of bug. Maybe they can adjust some tooltips here and there?
In case I actually missed in game notification of this mechanic, I stand corrected, of course. This is just meant as a heads up for those who were unaware.
