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.
