Not sure if this is a bug or a multi typos in the change logs but twice now since commands were added there have been bug fixes for game rules in the change logs but I have tried everything I can get them to work and have yet to find any indication of these commands being in pocket edition and I have also done a bit of googling and as far as the internet is concerned there is no gamerule commands in mcpe I'd be surprised if this was actually a bug because I think the devs would notice something like this so if it is just a typo (maybe it was supposed to say gamemode both times) I would be fine with that after all everyone makes mistakes I just would like to know steps to recreate wouldn't really work here as it isaabout a lack of a feature mentioned in the change logs
