However, he also has the supermarket problem; I first noticed this when he got an opportunity called A Lobster Crisis, which required him to go into the supermarket. Unfortunately, this was a day or two ago and I cannot recall anything I might have done, except I did receive a Flagrant System Error randomly which I now regret not taking a screenshot. I couldn't select the supermarket and clicking on the opportunity icon did nothing. I circumvented this problem by running SupCom on Collect: Seeds, which forced him to take care of the opportunity first. He was able to enter the supermarket that way, but after he completed the opportunity, he still was not able to interact in any way with the supermarket.
I had the unclickable grocery store problem, I fixed it by removing seeds from my inventory. Special seeds can be stored in the fridge so maybe the game treats them as spoiled food or something.
