Error: When using the Plugin BlueShop the signs dont seem to want to activate upon right clicking, this action should open a gui panel.
Error 2: When using the plugin iridescent The hex codes dont seem to want to work.
Reason: Only theory I have is that during an auto patch, it broke the signs functionality and hex code.
Upon trying to downgrade many errors popped up about loading newer chunks and would freeze on restart.
