Sand walls are a complete pain to build. It takes so much time and effort to make the walls, and it is just annoying. I was wondering if we can buy sand wall buckets that go in reverse. They can be $7000 for 16 buckets, and it will be very useful in base building. As I said before, just have it go up instead of down to save server lag. If not, we can keep it going down, but only 5 at a time in a 2 chunk area. I am not sure how this will 100% work, but I feel like we should all think about a solution as a community to make a type of automatic sand will maker.
