Edolicious pretty much speaks my mind on this topic. While it's a lovely idea that I'm sure a few people would love to have, it would feel a bit "lacking" to make our own map and cover it up with sparkles and paint as a way to make it look somewhat official. This is not to say that we don't enjoy making maps for you all- the event maps take plenty of time and hard work throughout the year as it is, and it's one of the things that we enjoy making for you guys. Creating a map would take much time, but there's really no certainty that it would turn out in the way we hope. It's a bit like taking a well-known product and trying to mimic it- the quality may be similar and even enjoyable, but you can't help feeling like there's something missing. If we were able to give you a download or update to the game, we wouldn't go half way. Instead of giving you one map just for the sake of doing so, I, and I'm sure many of the other staff members, would rather give you more than one, fix bugs that needed to be fixed, and give you a proper update. It all comes back to the fact that we don't have the materials to update the game properly. It's not that creating the map and setting up a download would be hard, but it wouldn't feel the same, and I would rather not try to force something into being official if it's not.
It truly is a lovely idea, and it makes me happy to see that you're suggesting a nice idea for the community. With all of the additional things going on with recent events, the staff team, and most of our lives in general, I'm just not sure if this is something possible at the moment. It's interesting to see everyone's thoughts here, though!
