I just notice in I game that I cannot research some plants and I don't know why. They are in the same stage and the option for research (pesquisar) and take a cut (pegar corte) is only available in s...
@jupkmn I just played your home for about 5-6 days in-game. Upon placing the home most (but not all) of the in-season plants, along with the out-of-season ones (I have seasons in my game, so a bunch of the plants you had stayed a dirt pile the whole time, as this happens when out of season.) I didn't realize until some of the Sim days passed that the plants on the right side of the house were trees - one in-season for me and one not. Neither of them turned to a tree yet the whole time I tested, plus at least one in-season plant still hadn't revived from dirt (though the rest that were in-season did), but all of that dirt fidgetiness (and some of the plant bugginess) I expect you're aware of...
All that said, I still had the expected interactions come up per gardening level for the same two Sims in my other test:
The Sim at gardening level 1 could only water (if it needed watering) or uproot.
The Sim at gardening level 10 could research or take a cutting (plus the additional options per level) from all plants that were in full bloom and in season.
Do you have Mods/CC, and have you tested this issue with them removed, along with the cache file? (I'm adding directions for this in the spoiler tag below - you could start a start a new game save and place this home and test in that... no need to open or save within any game saves that you have going, just as a way of confirming if any Mods/CC are causing the issue:
Try moving the Mods folder from your "The Sims 4" folder [Documents > Electronic Arts > The Sims 4] to your desktop (save it for reference) and delete the localthumbcache.package file in your “The Sims 4” folder. Then check in a new game save to see if this issue is still occurring. You can test without saving in order to identify which CC/Mods are causing the issue, then remove or add updated version(s) of the Mod/CC causing the issue.
