@SheriGR Hi, I played with base game only and noticed that I cannot research plants after fertilizing, harvesting or selling the harvest. Some plants stayed like that for many in-game days, to the point the evolution bar was ready to evolve, but the "evolve" action was also not available when clicking the plant. Weirdly enough the plants were ok when I saved the lot and them put it anywhere. For now, the only way I found to kind of correct this, is using "testingcheats on", clicking on the plant and setting it to "adult", it seems to do some kind of reset and all the actions become available. Note that the plants that I cannot do the actions are not dirt piles, they look like normal adult plants, but apparently they act like dirt piles. Some plants becomes dirt piles after fertilizing, but not all.
