I don't know, but I didn't change the data until I finished all the characters
I can not help more.
Perhaps the old bug was not completely fixed if it can still appear.
Can you provide debugging info, or stuff that might help the developer examine the situation?
You could tell for example is this a fresh install of 0.18.s, or 0.17 upgraded to 0.18.
I haven't updated the game, so it's 100% a direct install and not an update from 1.7 to 1.8
If there is no way, I will try the next version.
