I uploaded a save game before the bug occurs so you could test it on your end but I did not get a link to the uploaded file. It just said file uploaded successfully and it prompted me to upload another file. The bug is consistent and if you load the save file and fast forward the time to winter day 11 you will experience the bug (at least I managed to get it consistently). Save file has not been exported or upgraded from previous versions but the bug did occur on previous versions on different save files.
