Very serious material BUG

Change it quickly!!!
Different map archives and different people’s archives are double-threaded, so that if an attached file is built, some items are placed in the main city box, and after a while, the items are taken out and put on the body, and the files are read again, and the items in the box are still there, so the items become double out of thin air! ! ! ! !
Change it! ! ! !
This allows players to directly brush materials geometrically in a short time, which greatly affects the material system and trading system of the game! ! ! ! !
