If new crafting recipes become available, they don't show up in the interface unless you cause it to refresh in some way.

Example:

• Start out not having a recipe yet for ladders
• Open inventory and open the new crafting interface, with the compass tab ("all") selected.
• Manually craft a ladder. You'll see a toast about new crafting recipes being added.
• Look through the recipes.

Expected:
The new recipe will appear.

Actual behavior:
The new recipe doesn't appear.

Easy work-around:
Change tabs on the side or close and open the new crafting interface.
