Put (several) Batty Queens into an Industrial Apiary with Light, Lifespan (x4) and Seal Upgrade. As soon as the Queen starts working, the Apiaries UI closes and upon reopening, is totally empty (Bee gone, all Uprgades gone). I havent seen this behaviour with any other bee so far. Bdew said this was related to ElecCore, so here's the log. https://pastebin.com/42LwMWS9
