I planted sorrel, nettle and yarrow and waited with "-" looking at the plants.
I experienced plant evaporation while I sleep, so I forced energy to 100 with cheat engine.
Next day, while I still woke up, plants evaporated in front my eyes WTF
This also happened to the turnips.
These actions make plant evaporate after planting
1. Save and Load
2. walk away from farm
3. Entering world map
4. Fishing (maybe same as number 2)
5. Sleeping
6. Never look away and keep watching like scarecrow
Sami are you sure this is right agriculture system?
I noticed you already got things working by now, so I don't know if this was just a confusion or a real glitch.
But was it so that ALL the things you planted disappeared, or only some? This is relevant if I try to track things further.
If you plant those in spring they should start sprouting relatively soon. Also, if the are you tried to plant things is super full of stuff it's remotely possible that the game has had to emergency clear something, and the plants happened to be considered not too important. But in this case, you should have received hoard wisely warnings long before things are too crowded.
If things still seem odd in the future you can post a bug report and I'll give this a proper look.
Oh, OK I'll try explain it. I loaded it once so there were 2 attempt, so I'll separate it.
1) First Attempt of agriculture
At seedtime season, I planted 3 kinds vegetables; turnip, broadbean, pea, and 3 kinds of herbs; sorrel, yarrow, nettle. Vegetables sprouted normally. But when I planted herbs they all disappeared after save and load (and other actions I mentioned above), and never sprouted again even after late Fallow month. And this time I never saw "Woah, you're hoarding too much" warning sign. I peevishly planted turnip on the herb farm plot at late Fallow month, and this time, only a first few turnips sprouted and others disappeared (I had 3 farm plots separately and only first plot's turnip sprouted). And this time I saw "Woah" but I never knew that meaning and overlooked.
2) Second Attempt of agriculture
I loaded backed-up save file (It was Seedtime season at that point) and did same thing. What I mentioned above never happened this time(?!) I planted same things and this time herbs sprouted early fallow month, thanks to koteko. And everything worked normally.
