Wire connections cause all entities to stop rendering. the game must be restarted in order for objects to render again. I AM using optifine which is what seems to be causing the issue. obviously this should not be a priority, but it would be nice if this mod had optifine compatibility.

That's strange, are you using any shaders? If so does it work without?

Works for me, Must be your shader pack´, try using another shader pack.
