This is not a beta issue. I have newest version of Minecraft with a big problem.. when using furnaces to smelt, if you set 35 in each and let them cook..you can not add the stacks of 35 together anymore...they will not add to 64 with anything left over...when 3 or more packs the bugs even worse..the game takes some items from each pack to fill one, or from the full packs instead of near empty ones..this makes it extremely hard to move and organize any items. So much so that I can not play on my year old server because organization is frustrating....the problem started when update 1.2.13 released.. Please can you make it like it was in 1.2.11? The pictures provided show step by step the process.
