Okay, this isn't an issue with the item itself but rather a glitch with the updates to piercings and the generic genital removal function. I suspect a lot of your other uncommon crash reports that include "EmptySlot" are the same one.
Having trouble figuring this one out. Could I get a copy of your save to poke it with? All the vaginalCapacity checks in that dungeon's code appear properly setup, so having the character it happened on might help figure out what's wrong.
Ship combat was supposed to be turned off, but I guess it got flipped back over while Geddy was testing things. There should be an update rolling out to fix that.
Is this still a problem in the latest patch? If so, could you toss me a copy of your save so I can quickly reproduce the scenario? Thank you!
