Graphical bug with my resourcespack

Graphical bug with my resourcespack

Normally powder redstone would have to connect with others.

But then the powders were all parallel.

To reproduce the bug:
1. Download the texture pack and install it
2. Launch Minecraft, launch a solo part and place the redstone that points to the north or south (or vice versa, I do not really know)

It can there be errors in the text (I'm French and I use Google Translate)
