I attempted to download multiple different packs since 1.20 and they are still downloading to this day. Whether I bought it or got it from my Realms+ subscription, it doesn't download. Hitting cancel does nothing, and it can't be interacted with at all after clicking cancel. They are all stuck at 0% and do not advance at all. If this issue has already been fixed, (I don't think it has,) people who have dealt with it before that fix still have downloading items that won't download.
