All off the items you listed as unidirectional but only crafting when dragged from one to the other not the other way around are still crafting fine for me in the .95 patch. That is with saving before I try and dragging them to each other so tested both ways, perhaps the bug is not evident for everyone, which is why I was bringing it up, could be system issues or install issues or who knows what.
That's something that really confusing the matter. For example, I must have tried to combine an arrow-shaft and an explosive arrowhead dozens of times yesterday, across a dozen-plus games as a test. New games created after the patch, old saves created before the patch, 0 points in crafting, 1 point in crafting, 2 points in crafting, 3 points in crafting.. didn't matter. It would not combine to create an explosive arrow no matter how many different ways I tried.
Then, last night, a friend and I started a new game together. As she plays the Ranger (which starts with an explosive arrowhead in her inventory) I warned her about the problem. When we found a branch she combined it with her knife to create the arrow-shaft, and then combined the arrow-shaft with the explosive arrowhead to create an explosive arrow. It just worked, first try for her, for no apparent reason.
Since she was hosting I had her send me her save game file. I then loaded it, purchased another explosive arrow-head from the vendor in the first town, but could not combine it with an arrow-shaft. And the only difference was that (when she did it) her character was level 1, where as when I did it her character was level 2 (with no additional points in crafting).
That just makes zero sense.
