Further Information

Link to crash log: No crash
Steps to reproduce:

1. First step: Place Runic Altar
2. Second step: Place a valid recipe into the Runic Altar
3. Third Step: As the Runic altar is crafting, hover the cursor over the Runic Altar (so that the progress bar is shown)
4. Watch as the ENTIRE world disappears.

What I expected to happen: The Progress bar to be shown for the item WITHOUT the world disappearing

What happened instead: Rendering F up.

My first suspect was Immersive Portals, but deleting the portal did not solve the issue. Considering this has not been posted elsewhere on this Github, this may be a mod conflict.
