Disappearing Dirt

Saturday afternoon I headed down to Sunsong Ranch and harvested my plants - primarily White Turnips for Work Order: Golden Lotus II. I then set about planting seeds for the next day when something very bizarre happened.

I had an occupied plot. So I disturbed the vermin and killed it. But then the plot mysteriously disappeared. I reloaded my screen but it was still missing. I decided to carry on with the remaining plots and then go back to it. Another plot was occupied and exactly the same thing happened.

Missing plots.
