I seem to be getting an error with Random Bees from the bee attractor. I set up an automatic system to pull seeds from a chest, feed them into some squeezers, then pump the oil into my powered bee attractor, which then pumps the bees out into another chest. It was working for a few hours, and I've gotten several princesses, and quite a few drones. Now it seems to be crashing fairly frequently. The first few times I was doing other things while waiting for the bees to pile up, but this last time I was basically just waiting.

Here is error:
