I think it is possible you have deleted one of the events that roles the years but im not sure I will check now I never had this problem in the game im making or testing. I am gonna listen to you and check, nonetheless.

I found the fix and I will upload a new version of the template tomorrow.
The fix is pretty simple where it says on the bed event at the top
if the variable main days is 28
change that
variable to days of the season.
It seems that was an oversight of mine and I am very thankful you have brought that to my attention.
The making of this template took 120hours and I made this error as I first started with a different time system when I was experimenting with the time and crop growth design.
Thank you for bringing this to my attention.
