Yeah, my plants aren't growing after few stages. No weeds, no need to water and fertilize, they just freeze at particular stage of growth. And this aint cool for my green thumb sim. Planting new seeds aren't helping, they also freeze at particular stage of growth.
You're not alone in this, and your problem probably isn't fixed forever. I keep having this problem too. My plants get stuck exactly like you described. There is no option on the plants to tend, water, or fertilize and they never progress. I've found I can plant new seeds after this happens to my garden and those will grow for a few cycles and then quit. I've trashed this particular family's garden four times and started over. First I thought it was my mods. I took them out. Then I thought it was the fact that I kept changing the length of the life cycle in options right before the garden froze, so I started over and quit doing that. After that I made a new town and those plants froze after a while too.
I have no idea what is really causing it to happen. Has anyone who has had this problem and solved it figured it out?
