 The plants in the wilderness are gone, at least optically. You can hover over them and it tells you it's a rosebush but you can't see the bush or harvest it. The only visible thing is the little dirt pile they usually grow out of Plants on lots seem to work but they are never ready to harvest. When I noticed it I switched off all mods and I re downloaded the base game and seasons, but no change

Update:

So it seems as if the wild plants disappear once they have grown up to full plants. The little seedlings are visible. If the plants have already been in the world, they are visible (e.g. the little garden areas in Oasis Spring for example has a grown lemon tree that is visible and harvestable and the plants at the festivals in San Myshuno also show up and are harvestable). Does anyone know if this is being worked on? I play a lot with gardening and this is ruining the game for me quit a bit....
