We hadn’t intended to put out another patch so soon, but an odd bug was reported on the forums – putting an item in the hotbar, then placing it in the trash slot in your inventory, and then exiting the inventory window before the item was finished being removed was causing player files to become corrupted.
That’s fixed now! Any character that was broken by this specific bug should also be fixed, and should reappear in your character select screen.
We are still working on some bigger bug fixes and our first post-1.0 content update, but this was a big/critical enough bug that it warranted a quick fix of its own. :)
