Every time I try to click the "made using" box. Thankfully I lucked into compressing some caramel and making a comb on accident not long after I first made the post, but this error code is from just now.
Ah I see now. I think maybe I didn't program the recipe book to ever have an empty made using box. I should honestly put the hex mould in that slot, as it would make it clearer how honey is obtained and also fix the crash.
