[Embers 1.0.0] saving breaks leading to crash after winning

[Zeyphor]

After I won the game, things went normally, except the saving bar appeared on the right side of the screen and the save bar in the middle of the screen stayed at 0%
later I went to the item vault and the game crashed
then I reloaded and it put me right on the turn where I won, the end boss' loot was nowhere to be found, including the special super item that lets me do something special, and I didn't get to use the spoiler thingy right at the end on either thingy, nor was I told to check it out by the orcs who should've given me the keys to it

I was using classic UI mode and using only one addon, the old 1.1.5 orc breeding pits addon
