Received the following error sometimes when a slave has a child. In this case, the child was the spawn of a a taurus and a halfkin (wolf/taurus) in the farm. Not sure if this is an error in character gen, but I'm currently scouring through the save files to see if I can fix it directly without restarting from my last hard save. (Which was apparently over 100 days. I really don't wanna restart from there lol.) Compared the character's details with a working character's, and it looks fine, so I have no idea what happened.
This is the result of the error, after I reloaded several times from the autosaves. (The first time, the name was listed but clicking on it drags me to another slave's page. The second time, it showed up but the price at the slave guild remained Null.)
