I have a problem in my game - not sure if it's due to mods or if it's something which happens in vanilla.

I have moved into Severin Manor for one of my characters - he's completed most of Dragonborn's quests now, and has done pretty much everything major in the game, but still adventures about and finds new things to do. his main house used to be Breezehome, but now it's Severin Manor. I have a mod which changes the interior of the manor, but nothing which modifies Raven Rock at all. My problem is the first time I wandered into Raven Rock, for some reason I decided to harvest the Scarethraw plant just outside Severin Manor, and now it won't come back. The main decorative plant outside my house... and I plucked it and it's gone. If I leave the cell for 10 days, the scarethraw will respawn, but the next time I leave the cell and reenter it remains in its plucked state. Is this a vanilla bug or does it come from one of my mods? The only plant-related mods I have are one which lets me plant Nirnroot, and a greenhouse for my Lakeview Manor.

Same problem with another of my characters, who has this beautiful house in Lakeview. I installed Shezrie's greenhouse in the back, and it all looked so beautiful. Then for some reason when harvesting my plants I decided to harvest the Hanging moss which dotted the walls in the greenhouse. Now the Hanging Moss, which looked wonderful, has the same problem. If I wait 10 days and come back I see the moss hanging in all its glory, but if I leave the cell and reenter it's all gone back to the plucked state.

If this is a vanilla problem, is there any console command to make a plant respawn as harvestable? Disable and enable brings back a plucked plant, recycleactor, and "resetai" (a long shot, I know) doesn't do anything. With the Lakeview character I could probably disable the mod, save, and reenable the mod, but for the Severin manor plant it'd be horrible if I had to load a save previous just to get a nice-looking plant... Thanks for any help!

It's a vanilla bug and a pretty obscure one if you're not actually paying attention.

It affects more than just plants. Sometimes even monster spawn points. The cause is unknown, but it the engine does not properly "remember" spawn states on game load, or even cell load. Changing the respawn GMST via command or CK does not fix this.

there's no console command to make plants respawn, that I know of.

According to some sorces, this bug has been present since patch 1.3. There was a IMO worse respawn bug involving ash piles that was fixed in 1.6 - what that bug did was slowly empty your game. When you entered areas before the reset, the respawn timer would freeze indefinitely. You can imagine what your game would like, playing with that bug for severel months. However, the 1.6 fix did not fix the bug from 1.3.

There is no chance this will ever be fixed by beth. There's a mod that takes care of the plants.

Thanks so much! I'll get that fix asap.

Yeah, it's really obscure, and one that I'd never have noticed if those couple of plants were not in such a prominent place in/outside my houses. I'm sure I'd never have noticed if the blue mountain flowers between Riverwood and Helgen were pluckable or not...
