Very great plugin, can help u with planing economy, nicely prevents abusing players one source of money farming. I tested this plugin on 1.16 - work without any errors! thanks author.

Good Plugin but when i as a Payer use /mt pay player the first amount is not round even if it is true in config.

非常感谢这个插件带来的功能，但是似乎物品改了名字之后使用/mtadmin nbtset添加后会无法出售，是否可以兼容一下这个？非常感谢您发布这个插件，即使不兼容也帮助了我很多!

Please let him support ItemsAdder's items, I use nbt to add items, nothing works!

这个插件真的是太好了 玩家想要系统商店 别的插件需要设置 这个插件就直接能出售了 十分感谢作者能将这个插件支持到1.19 我的服务器很需要它 它可以让服务器货币变的更加流通

非常好的插件，我是中国人，我为这个插件感到自豪，我感谢这个插件作者的贡献，非常好的插件，我推荐更多的服务器来使用它，以保障服务器的平衡性，感谢作者，very good

very good, he solved the sad of my server economy
==========================================

这个插件非常不错，玩家非常喜欢，该插件可以很好控制服务器经济体系，不会让经济迅速膨胀而导致服务器经济体系超出上限，从而导致一些玩家游戏体验非常差，不利于服务器长久发展。

It is a useful plugins. I don't want any players have too much money so that they can group up and break the serve economic.
