Yesterday I started upgrading my enchanting table, but then when I placed down a bookshelf it stayed invisible and the number in my inventory never went down. It stayed invisible until I either left the game or broke a block, but that's not all. Even after the bookshelves are visible and around the enchanting table, it doesn't affect it's power. I thought it had to do something with my Minecraft files, (because recently I dealt with some ADWARE). But when I went to a normal, unmodded version of the game. It worked fine. I then began to think that it was my mods, but no... I checked every discussion page for every mod I had and there were no topics about what I was dealing with. That narrowed it down to forge, so I went to the GitHub page to report this exact same issue and they said to come report it here. I hope that somebody out here addresses this issue because I want the game to be funner and less prone to glitches. Thank you...
