I probably broke this. I already had 28 slaves and ended up capturing about 70 slaves in a run and got the error, repeating, with a game lockup. It's when I tried to enter the mansion with all of these slaves in tow. I'd love it if I could just keep the few I want and quicksell the rest when I get to town, but I have to either sell them all or sort through them in the mansion (and then differentiate the keepers by assigning them a job, as they're jumbled in the slave sale display).
