Ok I see the bug report on Mojang's site now. I guess I was just lucky I didn't run into the bug before updating. Software is weird sometimes Thanks

Hi, I’m just starting with mods, so sorry if this is a well know problem. It is a glitch I noticed fairly quickly after installing Forge and my first couple of mods. The first thing I tried was to empty the mods folder, and verified that the glitch happens with just Forge by itself. However it does not happen if I switch back to my Vanilla Profile in the Minecraft Launcher. The glitch happens when trying to place a block to the underside of another block, that is at the maximum reach. If I place the block on the side of an adjacent wall instead, or pillar up one more level, the glitch does not happen. This glitch manifests as the block showing up briefly and then quickly disappearing again. The inventory will be decreased on the first attempt to place the block, but clicking again will raise the inventory by one. This toggling of the inventory happens regardless of whether the second click is on the same location or a different location in reach. I have downloaded several versions of Forge and found the same behavior in all of them: 1.6.4-Forge9.11.1.965 1.7.2-Forge10.12.2.1121 1.7.10-Forge10.13.0.1180 1.7.10-Forge10.13.0.1208 fml-client-latest.log
