In correspondence with the unique events, it would be extremely useful to know which assignments allow you to "safely" remove a slaver so they can return on the special event, since supposedly some assignments remove them permanently, and there is essentially no in-game way to determine one from the other, along with the fact the event for a returning slaver seems to trigger extremely rarely (I've never had it occur).
By that same margin, knowing how many variations on returning slaver events, and the return events for the unique bimbo aspect "wounded" slavers there are, would be extremely helpful as well, since this stuff is nigh impossible to test.
Who knows how it might break the code, but if there was a way to manually trigger both types of return events in the Dicemod it would be interesting, assuming the return events aren't extremely underwhelming, but the way Bedlam phrased the changelog made it sound like the slavers get unique transformations.
