I thought so..

Did you look for this error? My personal question on this, and different person's question are within the first two pages. (One is eleven questions below yours, at the time of writing this.)

EDIT: I discovered that func_104112_b() and saveExtraData() are the same thing. removing func fixed the error.

 

If you remove

public void func_104112_b() {}

from the bottom of your class, you should be able to reobf, and release it.

Thanks SO much!!  I looked a bit but I posted about it before a while back and since nobody responded I thought it must be some weird thing with MCP or something, and kinda just started working on other stuff...

Glad it helped. Although use the search tool more often, some people are more blatant than I.

 

GL on your future modding endeavors!
