So I made an Ore Harvester and planted it. Stuck a wind harvester near to get power too. Yesterday, I gave each harvester plenty of money (enough for two days) and gave the ore harvester enough power to go for a good 10 hours.

Now, I come on this morning, check them. Both are running, although obviously the ore needs power.

But now, I can't access the "operate machinery" button on EITHER. Everything else on both works fine. I can deposit money, energy, rename, etc. But if I click the "operate machinery" button to get to my hoppers, nothing happens, as if I hadn't even selected that option.

Thanks in advance for any help you can offer.
