Do you have any idea what would cause this?

 

EntityMiner.java

https://github.com/KaminoCoding/CommuMod/blob/hotfix/bug-fix%2317/src/main/java/io/cyb3rwarri0r8/commumod/entity/EntityMiner.java

 

 

Show your code.

Whoops.. forgot to add that sorry.

No.

No.

No.

What would be the proper way to do it then? I learned that from tutorials so....

Don't you still need a global ID if you want an egg for the entity? Recent versions of Forge for 1.8 removed this requirement, but I don't think it was backported to 1.7.10.
