My friend uses your mod in the modpack on his private server, and we're having an issue where we can't seem to open the void chests we're finding in the End. Before you ask, no, we don't have any Void Keys (yet) but the chests we're finding don't seem to have locks on them either, so we didn't think that was the problem. Could you please enlighten us as to whether this is a bug or just a user error on our part?

--Edit: Never mind, I just found my own answer in the wiki (it is a user error). Sorry about that.
