Thank you

I am french : please no Abbreviation for me

delete the examplemod from ur project u wont need it.

It seems to be checking the example mod twice, I am guessing because you are using a lot of the same code, as Failender suggested deleting the original example mod should fix this.

Thank you.

I learn the modding and i follow the guide.

It's normal to are Sam's code.

I have deleted the exemple mod and minecraft don't crash.

Thank you thank you and thank you.

+2 thank you

Close please :D
