Craft bee eggs with a honey treat having any gene besides type gene causes crash.

I think the mod assumes there's only type genes and tries to get a bee from a gene that is not a type gene.

hmm, I have a specific check for that which must be failing. Did you swap out the honey treat after it had started incubating?

No, the honey treat stayed all the time in the incubator.
