Hi Michael, thanks for reporting this. We are aware of this issue. Please note the problem is only a display error where an additional day of building time is erroneously shown.

Hello Yunus, yep the problem isn't actually causing the building to be finished later than it was expected, but still can be a reason for unplanned tokens spending, especially for those who are not aware of that fact.
