All shop signs below chests seem to be broken. Attempting to use one returns error "Couldn't find a chest!". Attempting to create a shop sign below a chest fails as well. This isn't isolated to my shop on smp4, as I have tested other shops and had other players test it.It is such a massive bug that I assumed it had been found immediately and was being worked on. It has been quite a while though, and I can't find a reference to it on the forums anywhere. This affects hundreds (probably thousands) of shop signs across EMC. I guess its possible that many shop owners aren't aware that their signs aren't working.I'm not sure when it started happening, but it has been at least a week. Possibly longer, as I didn't buy anything for a while. Is this problem being looked at?
