There’s been a surprise, unannounced server update… and I don’t think it was intentional.
While we’re waiting for official word of what has happened, and what’s going to happen going forward, please post any bugs that you find here.
There’s already been word from keihdra that voidchests are broken. Whatever you do, don’t put anything new into your voidchests until we know what’s going to happen. The items won’t be lost, but they might take a temporary patch to get back. Items that were lost in voidchests are still there, they’re just inaccessible.
