[1.6.4] Derived Classes Don't Obfuscate?

[XVicarious]

I'm basing a mod around Thermal Expansion and I extend a couple classes from CoFHCore.  I don't know if it is intended or not, but classes that are derived from those CoFHCore classes (which in turn are derived from vanilla Minecraft classes (ItemBlock, and TileEntity specifically) cause odd errors where they don't obfuscate.  I tried not extending the class that was the easiest to reimplement (one method) and it worked until I ran into a case where the other extended class was used (the worldObj pointer) and it turns out that class wasn't obfuscated.  Is this a bug, its it intended, or did I just not set up my development environment properly? 

 

edit: I accidentally posted here instead of modder support, sorry. can a moderator move this thread please?

I'm not trying to obfuscate anything from CoFHCore.  and the classes arent in my mod.  But my classes that are derived FROM those classes aren't being obfuscated correctly.

No, I'm using latest for 1.6.4 I believe. I'm out right now so I can confirm that when I get home in about an hour and a half.

It all works after moving to forge Gradle.
