Crafting doesn't yield expected results

With the latest update, crafting multiple blocks is bugged.

Ex: One log when converted to planks should yield four planks. Doing one plank at a time yields the expected results. Attempting to create a full stack of planks from a full stack of logs only gives you a 1:1 return on planks. Attempting to create 12 planks from three logs will only give you 3 planks if done all at once.

 

This bug currently affects all objects that yield a return higher than one. Stairs, fence posts, planks, torches etc.
