I don't know if mine is glitching generally speaking, but I foolishly bought the Seasons expansion pack in the latest sale, and now my huge income that many of my Sims get from their gardens is completely down the drain. I worked out that you need to do your planting indoors so that you can still grow things out of season - as such I started building glasshouses. But I'm not getting anywhere near the same yields - what is that about? And is it fixable?
I suspected I shouldn't have got Seasons. For my kind of gameplay.... I was right. But everyone seemed to love it so much, so I thought I'd give it a go. I'll go with my instinct next time (nobody is going to convince me to buy Eco Living, in other words lol).
And yeah, there was one household where I think it was a glitch rather than my new addition of Seasons, where the household lost all their plants and had to regrow them in the subsequent days.
