Crash log

I've reproduced it in a pattern encoding terminal as well as a crafting terminal. The backtrace led me to believe that the FacadeRecipe was somehow involved. I guess it is somewhat similar to the problem here #7928 with the variable sized crafting grids in 1.21.

Steps to reproduce:

• place cobblestone in center slot
• place cable anchor in top slot
• place cable anchor in left slot
• place cable anchor in right slot
• crash

Whenever the lowest row is empty the crash happens. placing the bottom cable anchor first prevents the crash. The crash also happens when you remove the bottom cable anchor from a complete recipe.

Cool, thanks for the quick fix!

I was having a similar error with other recipes too, but come to think of it, it was always while filling the last row.

I'll test the update when I can and let you know if I still have issues
