It's maybe a bug but not like it has an error log so I write it here:

I made a "custom bed" actually a grave, the code is here:

https://github.com/Dawars/Easter-mod/blob/master/src/common/easter/blocks/EasterGrave.java

 

And the problem is that when I break the grave for the head block it'll brighter but the foot block will turn instead of the brighter foot texture it'll turn into the texture defined in the texture index but it'll use the texture from the terrain.png not the custom texture file I defined (in my case 21 a top log texture).

 

I hope it'll be fixed, thanks for reading!

Ya, no breaking texture on the top always bugged me, so fixed: https://github.com/MinecraftForge/MinecraftForge/commit/44e3843edbbbe9c7ba638ad1480555a71051827e
