That's some wonderful feedback right there!
The load times are becoming an issue so I've noted that one down and will look into it.
Your problem with the Beacon factory. Tell the bot to stand on the output tile of the beacon maker first, then tell it to pickup a beacon. That way it will only ever pick up the correct one (assuming there is one ready to pickup).
Most of your bugs and suggestions have already been noted but I've added your new ones. If you're interested you can find our lists here.
