How guys, I'm modding with Forge-10.13.2.1230 on Eclipse. Here is the case, i modded a custom inventory which i want to cover the original one with Key 'E'. And i read some tutorials about "IExtendedProperites", and i did make one. But here comes some problems. When I test in the Eclipse ( open server and client in the same and log in with IP:127.0.0.1), items in custom inventory works good. but when i separate code and compile into two jar file which just for client and server, and then log in. First time i clicked item in custom inventory, i can move , drag, click the item. After i place down a item into slot , second time i clicked it, the item just disappear strangely.
