Lost seeds, no plants or weed (turns out it's bigger than this, GAME BREAKING BUG)

[Meowish]

Also sent through in game bug reports. I left in the morning to go litter picking and left the plants and drying to my 6 botanists (2 botanists with 8 plants and 6 botanists with 5 drying racks). When I came back well after curfew ALL my seeds were gone, I had 30+ seeds per strain of weed. They are not in their shelves nor in my botanists inventory (their inventories are full with soil, the shelves with the seeds are set as their supplies). I can tell they also haven't grown any additional plants since I left, because the output for my dried weed barely went up, there is no weed on the racks currently drying or in the shelves set as output for the plants.

In case it matters my setup is as follows:
2 botanists with 8 plants each. Every strain has 4 plants. I have 2 shelves with seeds set as the supplies for those 2 botanists, 40 seeds per strain, so 1 shelf with OG Kush and Sour Diesel seeds and 1 shelf with Green Crack and Granddaddy Purple seeds. (at the time of seeds disappearing almost 1 stack of seeds had been used per strain, so roughly 30 seeds per strain left when I left the Barn). The output of the plants are set to be put in the right shelves for drying, I have a shelf for OG Kush, a shelf for Sour Diesel, one for Green Crack and one for Granddaddy Purple. The botanists tending to the drying racks take the weed off these shelves and when it's dried they put it in my "ready to pack" shelves, also 1 shelf per strain.

Restarting the day, as losing that many seeds AND not getting any weed is pretty crippling when I just spent all my money to buying these seeds and getting my botanists set up.

EDIT So I just restarted the day and I noticed one of my botanists standing next to the seed shelf, just continuously grabbing seeds, they're disappearing into the void. Not sure how to fix this, any suggestions would be massively appreciated.

EDIT 2 So, I took away the seeds so he couldn't steal them... He then went to trim the plants, the weed just disappears. Another botanist, who is supposed to be tending the other 8 plants is doing nothing, when asked why she says there's nothing to do, even though the plants are fully grown and the receiving shelves are empty. As I was keeping an eye on the first botanist, I just saw those fully grown plants disappear out of nowhere as well. I have no idea what's going on or how to save my save file... please someone help!

Turns out, after many hours of troubleshooting, this bug happens because the inventory if my botanist was full! Definitely in need of a fix or a clear warning at the very least. Glad it was less game breaking than it felt at the moment.
