Game mode: Online - Official Server
As far as i can tell this is gamewide. When you have a building item in your hotbar and you press it to craft you do not get the EXP, only if you inventory craft it.
Here is an example video i made, watch the EXP bar between the 2 crafts: youtu.be/qGwi-c57REI (Links were not allowed)
Iv tested it with blackice items and a few others, it seems to be all items.
