I am still playing one of the first games I started when the game first came out. It is a multi generation game and I always have a gardner sim. I have dragon fruit plants, bonsai and those space pod plants. The other day I was playing and had game in build mode and picked up one of the space pods and hovered over the sell icon. Said it was worth over 2000. I tried a few other plants and they all were different prices, basically over 1000. I was selling stacks of seeds from inventory for over 20,000, mostly dragonfruit. Well, yesterday, that all had changed. Space pods were back to being 100 each and seeds had dropped in price again. I assume it has to be a bug. Should have sold the plants when I had a chance, lol.
