Thanks to a note from Kidcodiwise, I found a bug in the system that kept donators longer at their donator status than intended. I originally made it so that a user’s donator level is being checked and downgraded (if applicable) when the user logs in. This would however keep users forever a donator in case they just never come back after being upgraded.
I now included that check in the lot reset process that runs every night, so your lot will reset properly if your donator status has expired. Tonight a couple of lots will reset accordingly.
