[1.16.5] Differences between Dev and real Environment

[Derican]

I'm devleloping mods for 1.16.5, and I test it working well in IDEA. But when I turn into mc launcher to play, error occurs and reporting bugs that does not exists in the source code.

I've tried:

- delete .\bin .\build and re-generate jar

- clean and re-generate jar

- invalidate cache and re-start

The forge version and other mods versions are the same. What's the problem?

Unkown block type: 'xxx:xxx'

It reports some blocks that I have deleted before. I searched for the block name but got no results. That's why I re-generate the jar multiple times.

And I've double checked the jar creation.

What error occurs? Also make sure you are creating the jar file correctly, refer to the documentation.

Post the generated jar file as well as a Git repo of your mod.

I found the crash may be cause by the name in nbt files. But I'm still confused why there's no crash when running in IDEA.
