This was broken in the patch almost a month ago. Why hasn't this been hotifxed? It makes splitting and positioning the party extremely clunky, annoying and unneccessarily slow. The issue was acknowledged at the beginning of last month so why the neglect?
Similarly, why was selecting multiple items still not implemented for the mouse interface? This was promised to be patched in five months ago!
I'm getting the feeling pc version is simply being ignored right now...
