My device is a Huawei Honor 5x. Every time I try to change my village in edit mode, I finish building a base and save, but several sections of wall are gone when it saves. This is not just the visual glitch where there is a small space between walls, the wall sections actually end up back in my inventory and I have to click around to put them back. After I fix it and save the second time, the walls stay. It is incredibly frustrating because I sometimes spend 20-30 minutes building a base and then have to spend another 5-10 minutes filling in walls that fall off my village. This started happening within the last several weeks. Any help would be greatly appreciated.
More information: I just tested some things and this only happens when I tap to place walls. If I hold down and drag to place my walls, they stay solid. This is not a satisfactory fix, since my device's screen is not large enough for me to accurately drag walls around my buildings.
