I found a redstone bug that could break some designs.

This confused me with a lot of my builds, but turns out there is a bug which can make certain redstone designs break if you make them in the wrong direction. This bug is only on the 0 and 2 directions.

I made this post to inform, and to ask someone with better grammar and spelling than I, to add this to the wiki.
