I just loaded in after not playing for nearly a month and am finding the same problem. I was going g to enter the greenhouse and noticed the shutters was closed and there doesn't seem to be a way to open them. Last time I'd played I'd restored the power but haven't figured out how to do the water yet. I'm mostly trying to play blind but I've tried to lookup this shutter issue after wandering around them for 2 hours. Any response (even a bad one) would be appreciated.
