Today when I was making a new character I noticed something strange. Under Second Umbral Moon, when selecting a date after the 7th, it would all be one day behind IE the 8th is said to be the 7th, 9th the 8th. This would stop at the 30th, as instead reads as the 28th, with the 31st and 32nd also being two days behind.
Checking other parts of the calender as well this seems to happen (with various degrees of have far off it is), but usually near the 30th mark.
