So, it's come to be a common theme that people tell me my sell signs aren't working, and it is almost always because they've got a block or mob egg in their hand. Whenever a new player comes to my shop and asks how to buy or sell, they almost always get stuck on this even if I specifically tell them to make sure they are using an empty hand.I somehow was under the idea that there was nothing which could be done to fix this, since it somehow had to do with how the events were sent to the server. However, players get back errors like 'You don't have permission to build here.', so obviously the requests are processed by the server. Is it really impossible to tell that the user was right clicking on a sign and not trying to place a mob or block?If this was fixed, it would be a huge benefit. I think every new player gets stuck on it at one point or another, even experienced players seem to fall for it now and again, and that's also a huge disadvantage for shops since motivated new players can provide quite a bit of stock.
