I had posted this issue here in minor detail but didn't follow it up as I rarely craft. I decided to look into it today and did some testing with a few friends.
This is what I see: Unusual crafting behaviour
This is what I should see (excuse the frame rate): Normal crafting behaviour
After having multiple people with various pings to the server (30-270ms) watch me craft, the end result was that nobody could see the glitch aside from me. Unfortunately I didn't have the foresight to make sure other players could see the glitch before making the videos, turns out I wasted my time. Feel free to craft anywhere you like, at this stage I see no reason to worry about this glitch.
