Engie tune up is being interrupted by generator state change

Having this problem too on Windows. Setting an OR gate with a dupe sensor to keep it on when the smart batteries fill up doesn't seem to help either, still leaves when the smart batteries send a red signal.

Worse, it seems that it doesn't just interrupt: it removes the task entirely. Locked the Electrical Engineer in the power room and they just went idle until the smart batteries triggered the green signal again.

Wow, the interrupted task by battery signal might even arguibly be intended behaviour, but the OR gate with dupe sensor is totally a bug.

Setting the doors to the room to auto instead of open worked to fix this for me.  Still no idea why it happens.

Just wanted to necro this to complain how I had the same issue, but I actually figured out why it was happening. If you put the Power control station in between Petroleum Generator and the Smart Battery, you likely got your Automation wire through the Power Control station Automation input by accident. So when the Red signal turns off the Generator (Or sends one Red signal to the OR Gate), the Power Control station also shuts down, and without it you can't use Engie's tune up.
