Assuming its when we try to make the Diamond Bees Breed, but we have had two crashes back to back when interacting with the bees. Here is the crash log

crash-2020-05-10_23.11.42-server.txt

It seems to happen with all bees that do not have any breeding rules to create a new offspring.

Is this on 0.1.4 and which two bees were you trying to breed?
