If I write out a sign and hold control + middle click, it copies over the NBT Tag as shown here: But whenever I try to place the sign, it acts as though it is a new sign without any +NBT tag/code added to it: I'm playing on Minecraft 1.8.9-Optifine and my server is Spigot 1.8.8-R0.1-SNAPSHOT, please help! EDIT: I just wanted to add, it works fine in singleplayer
