it seems like no matter what number I configure for the stacking percentage, items of the same type created even within the same minute don't stack at all =/

I can't duplicate this issue. For example, I killed four cows in short succession. I had four stacks of meat in my inventory. I was then able to stack all four stacks of meat into one stack.

I've added a bug report template to the project, including a log file request. Please add a log file to this issue when duplicating the problem. Thanks!
