It doesn't send signal if lever is connected to redstone but it does when its placed directly on the block, for exemple on a command block..

@SurprisedBH Please provide us with more information. What version of Spigot and SignShop? Could you provide some screenshots of how they are placed when it does not work and when it does. During development testing it works with redstone for me so we need to narrow down what is different.

@SurprisedBH I am closing this issue due to lack of information and not being able to reproduce it. Please reply with more information if you want it reopened.
