Stack Splitting/Merging bug
Can't split on top of existing stack of different quality
To produce this bug:
Stack of 50[any item in some quality]
Stack of 100[same item in different quality]
Shift+Click the 100-stac and type "#" to pickup from it
Now click the existing stack of 50. Doesn't merge the # into the 1st 5, and gives an error "You can't split this to here"
Items would merge just fine without item splitting.
