I am not Sure, what to send to explain or reproduce this issue. I am running v4.6 in a Multiplayer Server.
When trying to craft ANYTHING, the crafting bench shows the results for like 50ms and then vanishes (visual bug), I can still craft it.
The problem is, that for recipes that require me to switch using Polymorph (same recipe for multipe items), I can't do that.
